Improves: GitHub handling, AppServiceProvider and 500 error message rendering

[peaklabs-dev]

Changes

• feat: Added Purify for better HTML sanitization
• fix: render html on 500 error pages correctly

github.php:

• fix: GitHub JWT token timing issue (more information about this issues here Expiration time' claim ('exp') is too far in the future probot/probot#1426).
  • issuedAt -1min -> this is to avoid token not yet valid issues
  • expiresAt +8min -> this is to make sure the token is not valid longer then 10 min (to avoid the issue described in the linked issue) as tokens have to have a lifespan of less then 10min, this should help with time differences of less then about 1min (most cases) - as the total valid time is 9min (with the -1min) -> for any case of over 50s time out of sync (System vs GitHub API time) it will throw an error.
• fix: Expiration time' claim ('exp') must be a numeric value
• refactor: rename functions to make code more clear
• refactor: use camel case on functions consistently
• refactor: consolidate code
• refactor: better error handling in github.php and GithubAppPermissionJob.php

AppServiceProvider.php:

• feat: Configure commands for production
• feat: Configure modals for better error handling
• chore: remove unused authentik stuff
• refactor: move things to separate functions
• refactor: improve password security by not allowing compromised passwords

Issues

• fix [Bug]: claim ('exp') is too far in the future #4702
