Refactor core structure and notification UI

Major refactor to centralize QBCore and replace the web UI stack:

- Move QBConfig into a unified QBCore.Config and initialize QBCore.PlayerData; add shared/functions.lua.
- Remove legacy client/main.lua and server/main.lua exports and update fxmanifest to include shared/functions and drop those main scripts.
- Update client event handling: adapt player data events to QBCore:Client:OnPlayerUpdated and trigger job/gang update events; remove deprecated exploitable handlers.
- Web UI rewrite: remove Vue/Quasar dependency and config module; implement a lightweight vanilla JS notification system (html/js/app.js) with updated html and css assets, plus drawtext tweaks.
- CSS overhaul for notification styling and animations; HTML head/meta/font cleanup.
- Server fixes: use QBCore.Shared.Locations in teleport command and strengthen numeric parsing/validation for coords.
- Add .gitattributes for consistent text/eol handling and small code cleanups (thread/comment removal).

These changes consolidate config/shared logic under QBCore, simplify the frontend dependencies, and fix a few parsing/event issues.
