Bug 40811: Implement dual API for file transports with simplified auto-management
This patch implements a dual API design for Koha::File::Transport, providing
both a simplified auto-managing API and a traditional explicit API for maximum
flexibility and ease of use.

DUAL API DESIGN
===============

Simplified API (Recommended):
  - Automatic connection management (no connect/disconnect needed)
  - Flexible per-operation directory control via options hashref
  - Stateless operations safe for concurrent usage

  Example:
    $transport->upload_file($local, $remote, { path => '/custom/' });
    $transport->download_file($remote, $local);  # Uses download_directory
    $transport->list_files({ path => '/incoming/' });

Traditional API (Explicit Control):
  - Manual connection/directory management when needed
  - Stateful directory operations via change_directory()
  - Ideal for multiple operations in the same directory

  Example:
    $transport->change_directory('/work/');
    $transport->upload_file($local, 'file1.txt');
    $transport->upload_file($local, 'file2.txt');
    my $files = $transport->list_files();

The APIs can be mixed - calling change_directory() explicitly switches to
manual mode and disables auto-management for subsequent operations.

STANDARDIZED TEMPLATE METHOD PATTERN
=====================================

All transport methods now follow a consistent pattern with clear separation
between public API (parent class) and protocol implementation (subclasses).

Public methods in Koha::File::Transport:
  - connect()          → Resets directory state, calls _connect()
  - disconnect()       → Resets directory state, calls _disconnect()
  - change_directory() → Sets manual mode flag, calls _change_directory()
  - upload_file()      → Manages connection/directory, calls _upload_file()
  - download_file()    → Manages connection/directory, calls _download_file()
  - list_files()       → Manages connection/directory, calls _list_files()
  - rename_file()      → Ensures connection, calls _rename_file()

Subclass responsibilities (SFTP/FTP/Local):
  - Implement _connect() - Protocol-specific connection logic
  - Implement _disconnect() - Protocol-specific disconnection logic
  - Implement _change_directory() - Protocol-specific directory change
  - Implement _upload_file() - Protocol-specific upload logic
  - Implement _download_file() - Protocol-specific download logic
  - Implement _list_files() - Protocol-specific listing logic
  - Implement _rename_file() - Protocol-specific rename logic
  - Implement _is_connected() - Protocol-specific connection check

Test plan:
  prove t/db_dependent/Koha/File/Transports.t

Bug 38489: Add disconnect method and proper connection cleanup to file transport system
This patch adds proper connection cleanup functionality to the file
transport system, addressing a gap identified during EDI migration.

Changes:
- Add disconnect() method to base Transport class interface
- Implement SFTP disconnect using connection->disconnect()
- Implement FTP disconnect using connection->quit()
- Add DESTROY methods to ensure connections are cleaned up on object destruction
- Local transport includes no-op disconnect for API consistency

This ensures that FTP/SFTP connections are properly closed, preventing
connection leaks and potential resource exhaustion issues.

Bug 38489: Add rename_file method to transport system and Local transport class
This patch enhances the file transport system with file renaming
capabilities and adds a Local transport class for development/testing.

Changes:
- Add rename_file() method to base Transport class and SFTP/FTP subclasses
- Create Koha::File::Transport::Local for local directory operations
- Add 'local' transport type to polymorphic mapping
- Update transport instantiation to handle Local transport
- Add Local transport tests to verify polymorphic behavior
- Enhanced connect() method for Local transport validates directories

The rename_file functionality is needed for EDI file processing workflow
where files are renamed after download to mark them as processed.

Bug 39190: Rename API from sftp_servers to file_transports
This patch renames the entire API structure from SFTP-specific to generic
file transport terminology to reflect the polymorphic nature of the system.

API Changes:
- Endpoints: /config/sftp_servers -> /config/file_transports
- Parameters: sftp_server_id -> file_transport_id
- Definitions: sftp_server -> file_transport
- Controller: Config::SFTP::Servers -> Config::File::Transports

File Changes:
- api/v1/swagger/definitions/sftp_server.yaml -> file_transport.yaml
- api/v1/swagger/paths/config_sftp_servers.yaml -> config_file_transports.yaml
- Koha/REST/V1/Config/SFTP/Servers.pm -> Koha/REST/V1/Config/File/Transports.pm
- t/db_dependent/api/v1/sftp_servers.t -> file_transports.t

Updated References:
- swagger.yaml: paths, definitions, parameters, tags
- Template JavaScript: API URLs and variable names
- Controller: package name, variable names, error messages
- Tests: endpoints, parameters, descriptions
- API mapping: to_api_mapping field name correction

To test:
1. Apply this patch
2. Run: yarn api:bundle (to regenerate swagger bundle)
3. Run: prove t/db_dependent/api/v1/file_transports.t
4. All API tests should pass
5. Verify admin interface uses new API endpoints
6. Test CRUD operations work correctly

The API now consistently uses 'file_transports' terminology matching
the polymorphic file transport system that supports FTP, SFTP, and
future transport types.

Bug 39190: Fix circular dependency causing C3 MRO failures
Resolved circular dependency chain:
Transport.pm → TestTransport.pm → Transports.pm → SFTP.pm → Transport.pm

Changed 'use Koha::BackgroundJob::TestTransport' to runtime 'require'
in the _post_store_trigger method to break the dependency cycle.

This fixes the C3 method resolution order failures in
Koha::File::Transport::FTP and Koha::File::Transport::SFTP.

Bug 39190: Re-implement the connection testing
We now use background jobs triggered by Transport->store to update the
connection status.

Status is now a json blob with more details, so we update the api
definition to reflect that.

Bug 39190: Add key handling to SFTP Transports
We add triggers to store in the base class and then use them in the SFTP
transport class to write out the key file to the filesystem for later
use in connect.

Bug 39190: Rework (S)FTP into File::Transport classes
This patch adds polymorphic transport classes to Koha for FTP and SFTP
file transport configurations.

We introduce a base class for interacting with the base configuration
storage and subclasses to impliment the protocol specific transport
handling.
