Refactor quote approval handling and database schema

- Removed ReactionsHandler from service registration as approval flows now utilize interaction buttons.
- Introduced QuoteApprovalMessage model to manage quote approval messages with properties for QuoteId, ApprovalMessageId, Score, InsertDate, Type, and Approved status.
- Created migration to establish QuoteApprovalMessages table and removed the obsolete QuoteApprovals table.
- Added QuoteApproval model to track user approvals associated with QuoteApprovalMessages.
- Updated database context and migration files to reflect new schema changes.
