feat: Enhance club payment claims and task automation

- Added `paid_amount_cents` column to `club_payment_claims` for better tracking of payments.
- Implemented compatibility checks for the new column in `clubPaymentClaimService` and `clubTaskAutomationService`.
- Updated various views to handle read-only states when editing is not allowed.
- Refactored forms in `ClubAccountsView`, `ClubInvoicesView`, `ClubTasksView`, and `ClubCommunicationView` to use factory functions for cleaner code.
- Introduced a new migration script to add the `paid_amount_cents` column if it doesn't exist and initialize it for existing paid claims.
- Created a detailed plan for enhancing club features and ensuring stability in existing modules.
