Rework SQL field length (#5788)

* SQL auto-update field length
Follow-up of https://github.com/FreshRSS/FreshRSS/pull/5756
Only for PostgreSQL and MySQL / MariaDB. Not possible for SQLite

* Account for MySQL 65535
Partial revert of https://github.com/FreshRSS/FreshRSS/pull/5756
> The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead.
