This update replaces older accounting error handling with clearer, standard user-facing error types, helping users receive more consistent messages when something goes wrong. It also lowers the priority of expected warning logs so monitoring tools like Sentry focus on real issues instead of routine user errors.

Using UserError, AccessError, MissingError, ValidationError instead of except_orm and except_osv.
Using _logger.info instead of _logger.warning to avoid polluating Sentry

A small typo was fixed in internal documentation text. This improves clarity for people reading or maintaining the software, with no expected impact on day-to-day business operations.

The database manager now uses a newer shared date and time library instead of older separate tools. This reduces outdated dependencies and helps keep the interface easier to maintain without changing the main business workflow.
