Refactor txAdminLogs to modular, configurable system

Replaces the old txAdminLogs implementation with a modular, table-driven system. Adds new files (fxmanifest.lua, main.lua, settings.lua, utils.lua) and removes the previous monolithic scripts. Logging is now fully configurable via settings.lua, supports per-event webhooks, and features improved formatting and timestamp handling. Updates README with new installation and configuration instructions.
