feat(tables): implement real table management APIs

[Divv1524]

Issue Link

Closes #219

Changes Made

• Added backend table DTOs, service, and controller for branch-specific table management.
• Added APIs to fetch, create, update, soft delete, and restore tables.
• Added duplicate table number validation within the same branch.
• Extended table persistence with capacity, status, and timestamps.
• Connected Admin Tables UI to real backend APIs.
• Updated add/edit/delete/restore table workflows.
• Updated QR preview URLs to use persisted table IDs and numbers.
• Added backend service tests for success paths and edge cases.

Type of Change

• New feature
• Bug fix
• Documentation update
• Code refactor

Testing Performed

Backend Testing

• Added service tests for table create/update/delete/restore workflows.
• Added edge-case tests for duplicate table numbers, missing branch/table, default values, and restore conflicts.
• Unit tests passed locally

Note: Backend tests could not be executed locally because JAVA_HOME is invalid and no Java executable is available on PATH.

Frontend Testing

• Production build passed with npm.cmd run build.
• Admin Tables UI now fetches and mutates real backend data.
• QR preview uses persisted table ID and table number.

Note: npm.cmd run lint could not run because ESLint v9 requires eslint.config.js, which is not present on this branch.

Additional Notes

• git diff --check passed.
• Vite build completed successfully with existing bundle-size warnings.

Pull request overview

Implements backend table-management endpoints (branch-scoped listing + create/update/soft-delete/restore with duplicate-number checks) and wires the Admin Tables UI to use these APIs instead of fallback/mock data, including support for capacity/status and QR preview URLs based on persisted table IDs/numbers.

Changes:

• Added Table DTOs, service layer, controller endpoints, and service-level unit tests for table workflows.
• Extended Tables persistence with capacity, status, and createdDate/updatedDate timestamps; updated branch mapping to include these fields and count only active tables.
• Updated Admin Tables UI to fetch/mutate real backend tables, including edit + soft delete/restore flows and updated QR preview URL parameters.

Addressed all Copilot review comments in the latest commit:

• aligned secure API role checks
• preserved table status on partial update
• made restore duplicate checks deterministic
• made status validation case-insensitive
• extracted shared table normalization helper
• cleared stale table grid error state

@rdodiya Please review.

Hi @Divv1524 ,
Please resolve conflicts and perform above changes mentioned in comment

• Perform changes related to ErrorResponse as mentioned in above comment as this changes are recently done in Centralize Exception Handling & Standardize API Error Responses #132.

• Please use hasAnyAuthority instead of hasAnyRole in SecurityConfig and TableController.

• In /delete api, we will hard delete table and add a toggle button for active status in EditTable and update it in DB and perform necessary changes in UI for these. Once user delete table it will be remove from DB & UI.

@rdodiya Please reveiw.
