[FEAT]: Add pagination to Job Applications table / Implement Caching with Next.js

[lnovitz]

Is there an existing request for this feature?

• I have searched the existing issues

Is there a pain point in the app driving this feature request?

Large datasets (1000 apps) slow down page load and scroll, negatively impact user experience and application performance

Desired Behavior

Optimize dashboard data loading

Criteria for Completion

• Implement time-based revalidation (every hour? idk if this makes sense)
• If cache refresh fails, serve last cache

Anything else?

Please follow this YouTube tutorial: https://youtu.be/Wf8QRkuxgq4?si=cMMmKR16VS253fga

Should be able to do this all in Next.js

Frontend pagination is dealt with in another ticket (#352) - focus only on caching in this ticket.
