Refactor email search with new filter models

Browse Source 
Replaced the old `SearchFilter` with the new `MailSearchFilter` model to enable more flexible and granular email search criteria. Introduced `DateFilter`, `UidFilter`, and `MailSortOrder` to support advanced filtering options such as date ranges, UID ranges, and sorting order. Updated `IImapEmailService` and `FetchEmailsQuery` to use the new models.

Added validators (`DateFilterValidator`, `MailSearchFilterValidator`, `UidFilterValidator`) to ensure input correctness. Refactored `LimilabsImapEmailService` to dynamically construct IMAP search queries based on the new filter properties, supporting unseen messages, text filters, and client-side attachment filtering.

Improved maintainability and scalability by cleaning up redundant code and leveraging the new models and validation framework.
