* Use local timezone for recorder connection
The fix in #90335 had an unexpected side effect of
using UTC for the timezone since all recorder operations
use UTC. Since only sqlite much use the database executor
we can use a seperate connection pool which uses local time
This also ensures that the engines are disposed of
when Home Assistant is shutdown as previously we
did not cleanly disconnect
* coverage
* fix unclean shutdown in config flow
* tweaks
* Ensure sql sensors keep working after using the options flow

* ensure saving the options flow fixes the broken config entry
* ensure options changes take effect right away
* Add cover to validate the reload
