Bug 38384: Refactor plugin loading to use lightweight Koha::Plugins::Loader
This patch addresses the circular dependency issues and code quality
concerns identified in QA by introducing a clean architectural solution.

Changes:

1. Created Koha::Plugins::Loader - A lightweight plugin loader with
   minimal dependencies that can be safely called during early
   initialization. Uses DBIx::Class when available for proper
   transaction support, falls back to raw DBI for early init.

2. Added Koha::Database::table_exists() - Consolidated table checking
   logic into a reusable method that can be called as both class and
   instance method.

3. Simplified C4::Context BEGIN block - Reduced from ~120 lines to
   ~13 lines (91% reduction). Removed XML::Simple dependency and
   manual database connection code.

4. Updated Koha::Plugins::get_enabled_plugins() - Now delegates to
   the Loader module for consistency.

5. Updated C4::Installer::TableExists - Delegates to the new
   Koha::Database::table_exists method.

This addresses all QA concerns:
- Eliminates XML::Simple usage (David Cook)
- Uses Koha::Database instead of manual DBI (David Cook)
- Reuses table checking logic (Nick Clemens)
- Eliminates circular dependencies (Paul Derscheid)
- Much cleaner and maintainable code

Test plan:
1. Run tests:
   prove t/db_dependent/Koha/Database.t
   prove t/db_dependent/Koha/Plugins/Loader.t
   prove t/db_dependent/Koha/Plugins/Plugins.t
2. All tests should pass
3. Install and enable a plugin via the UI
4. Verify plugin hooks are called correctly
5. Verify no regressions in plugin functionality
