Onboard first test client

[woolfg]

• [x] database
• [x] metabase incl. https url
• [x] connector (cron)
• [x] apple auth
• [x] receive spotify/apple tokens from client -> send out email

[woolfg]

• Chrome extension ready, instructions on https://openpodcast.dev/#connect should work -> ready to send the data to the first client

[woolfg]

for the apple auth we use the current running endpoint -> maybe we need a proper auth/key?

AFAICT this is done and can be closed.

[woolfg]

we still need a "running" stack for the client

[woolfg]

everything up and running. call with first client next week to explain everything
