chore(supabase): fix supabase-realtime

[CollectiveUnicorn]

These changes makes supabase-realtime functional both on the admin dashboard and for external connections:

• Adds missing mandatory environment variables
• Adds route for supabase realtime's API in addition to the one that exists for websocket connections
• Runs built in supabase realtime db seed command on pod startup to setup tenant
• Updates all variables to use the name supabase-realtime as the db entries, routes, and envs all need to use the exact same name
• Bumps the Supabase version to bring in the latest (significant) realtime refactor and pull in the newly functioning realtime migrations
• Creates _realtime schema on realtime pod start to segment realtime tables from the rest of the db
• Sets db wal_level to logical as supabase realtime uses the data produced by the WAL and requires a minimum wal_level of logical to get the data required for RLS to function
