Improve mobile vault listings

[miohtama]

Why

Mobile vault listings used a wide, high-density desktop table treatment that made filtering and scanning difficult on narrow screens.

Lessons learnt

In this fixed-width table, off-screen elements such as sparklines and wrapped TVL values can define visible row height. Validate table overflow across loaded rows at a mobile viewport rather than relying on CSS intent.

Summary

• Compact the mobile vault heading and place all filters inside a Filters disclosure.
• Tighten mobile table rows, constrain vault and protocol labels, and prevent narrow data columns from overflowing.
• Add Playwright coverage for mobile filter interaction and label wrapping.
