feat: refactor tables to TanStack Table and consolidate components

[prakharsingh-74]

fixes: #85

Description:

This PR transitions the dashboard's table implementations from a purely MUI-based approach to using TanStack Table. This refactor addresses the previous fragmentation by consolidating table logic and UI into a more maintainable, "headless" architecture.

Core Improvements:

• Architectural Shift: Migrated JobTable, PodsTable, QueueTable, and PodGroupsTable to utilize @tanstack/react-table. This leverages industry-standard data management while keeping our custom MUI styling.
• Component Streamlining: Removed the overhead of managing 10+ separate Header and Row files. Each table's structure is now defined via a clean columns configuration within its primary component.
• Unified Filter UI: Introduced a generic TableFilterMenu component. This ensures that filtering interactions (Namespace, Status, etc.) are perfectly consistent across the entire application.
• Performance & Scalability: Improved handling of sorting and filtering operations, ensuring the dashboard remains responsive even with larger Kubernetes datasets.

Cleanup:

• Deleted Redundant Components: Cleaned up the file tree by removing resource-specific headers, rows, and individual filter menus.
• DRY Principles: Consolidated duplicated logic for status chips and date formatting within the new table definitions.

Code Review

This pull request introduces @tanstack/react-table to manage data and rendering for the JobTable, PodGroupsTable, PodsTable, and QueueTable components. It renames JobFilters to TableFilterMenu, updates its event handlers, and integrates edit and delete dialogs directly into the table components, allowing for the removal of several redundant sub-components. I have no feedback to provide.
