Fix up API handling logic for keys and set a prefix on all keys

+This release also changes API key behavior — "client" keys belonging to admin users can now be used to access
+the `/api/application` endpoints in their entirety. Existing "application" keys generated in the admin area should
+be considered deprecated, but will continue to work. Application keys _will not_ work with the client API.

 ### Fixed
 * Schedules are no longer run when a server is suspended or marked as installing.
 * The remote field when creating a database is no longer limited to an IP address and `%` wildcard — all expected MySQL remote host values are allowed.

 * Additional permissions (`CREATE TEMPORARY TABLES`, `CREATE VIEW`, `SHOW VIEW`, `EVENT`, and `TRIGGER`) are granted to users when creating new databases for servers.
 * development: removed Laravel Debugbar in favor of Clockwork for debugging.
 * The 2FA input field when logging in is now correctly identified as `one-time-password` to help browser autofill capabilities.
+* Changed API authentication mechanisms to make use of Laravel Sanctum to significantly clean up our internal handling of sessions.
+* API keys generated by the system now set a prefix to identify them as Pterodactyl API keys, and if they are client or application keys. This prefix looks like `ptlc_` for client keys, and `ptla_` for application keys. Existing API keys are unaffected by this change.
 
 ### Added
 * Added support for PHP 8.1 in addition to PHP 8.0 and 7.4.

 * Adds command to return the configuration for a specific node in both YAML and JSON format (`php artisan p:node:configuration`).
 * Adds command to return a list of all nodes available on the Panel in both table and JSON format (`php artisan p:node:list`).
 * Adds server network (inbound/outbound) usage graphs to the console screen.
+* Adds support for configuring CORS on the API by setting the `APP_CORS_ALLOWED_ORIGINS=example.com,dashboard.example.com` environment variable. By default all instances are configured with this set to `*` which allows any origin.
 
 ### Removed
 * Removes Google Analytics from the front end code.
+* Removes multiple middleware that were previously used for configuring API access and controlling model fetching. This has all been replaced with Laravel Sanctum and standard Laravel API tooling. This should make codebase discovery significantly more simple.
