feat: allow user to use other forges

[aaa006bd]

• load forge from db
• login via configured forges (initally github for now)
• allow user to connect additional forges
• add github as initial forge on start from .env
• save forges accessToken and refreshToken to DB
• refresh forge accessToken if needed (before using forge client)
• add endpoint to load user profile and use the user data in UI (avatar)
• refresh user jwt cookie if needed
• allow user to add repo from one of the connected forges (select connected forge first, search for repo)
• add new repo to database when user selects to add it (currently part of the indexing endpoint)
• add separate indexing endpoint (should almost be done using the current endpoint)
• load active repos from database (currently loaded by looping folders)
• fix passing credentials to clone api endpoint
• use netrc credentials to clone private repos

@aaa006bd Instead of storing the access and refresh token expiration dates you could use the jwt library and decode the token as the expiration date is saved in the token as well

Thanks for mentioning it. I forgot about these.

@aaa006bd I did quite some cleanup and pushed some improvements. Could you test the whole app on your system (searching and indexing github & gitlab repos, chatting with both repos) as well.

@anbraten sure. I am a bit busy today. I will do it tomorrow and update it in this PR.

@aaa006bd Last remaining issue is that we get an error when using the accesstoken to clone repos from gitlab:

remote: HTTP Basic: Access denied. The provided password or token is incorrect or your account has 2FA enabled and you must use a personal access token instead of a password. See https://git.geprog.com/help/topics/git/troubleshooting_git#error-on-git-fetch-http-basic-access-denied
fatal: Authentication failed for 'https://....git/'
