Return database values in GET endpoints; add overrides info route; remove comments

- GET endpoints now return raw database values (not overridden values)
- Created /api/admin/overrides route that returns which fields are overridden by env vars
- Removed comments from POST endpoints
- Admin panel can now show database values and display indicators for overridden fields
