refactor: eliminate proxy functions, migrate to direct class method calls

312 files changed, 2866 insertions(+), 24110 deletions(-)

Proxy function replacements (130+ functions):
- goHome() -> AdminHelpers::goHome()
- checkPermissions() -> PageAuthorization::checkPermissions()
- getBouquet/getCategory/etc -> Service::getById()
- deleteStream/deleteLine/etc -> Repository/Service::delete()
- APIRequest/systemapirequest -> ApiClient::request/systemRequest()
- prepareArray/preparecolumn -> QueryHelper methods
- confirmIDs/parserelease/etc -> AdminHelpers methods
- getSettings/clearSettingsCache -> SettingsManager methods
- destroySession -> SessionManager::clearContext()
- getMag/getEnigma/deleteMAG/etc -> MagService/EnigmaService
- getSeriesTrailer/getMovieTMDB/etc -> TMDbService methods

Removed legacy files:
- src/includes/admin.php (main proxy hub)
- src/includes/libs/ (35+ files moved to core/modules)
- src/includes/python/ (moved to bin/python)
- src/includes/api/ (moved to Controllers)
- src/includes/ts.php, reseller_api.php
- src/infrastructure/legacy/admin_proxies.php
- tools/run_scan.sh, update_redis_conf.sh

Additional fixes:
- SQL query placeholder migration (BouquetService, CategoryService)
- PHP 8.x null-safe access (live.php, server_view.php, stream.php)
- TmdbCron: extracted variable for repeated similar_text calls
