PHPStan prepare exceptions (#6037)

Take advantage of
https://phpstan.org/blog/bring-your-exceptions-under-control

Minimum changes to pass `tooWideThrowType` and `implicitThrows`.

Revert some mistakes from:
https://github.com/FreshRSS/FreshRSS/pull/5504
Preparation needed before new PRs of the same type:
https://github.com/FreshRSS/FreshRSS/pull/5962

Fix several wrong PHPDocs and catches:

> Method ... has ...Exception in PHPDoc @throws tag but it's not thrown.

> Dead catch - ...Exception is never thrown in the try block.
