feat(ui): streamline validator directory browsing

[JSONbored]

The validator directory currently puts secondary analysis ahead of the operator list and offers financial columns whose source needs further work. This revision puts a compact summary, search and readable operator rows first, preserving the existing paper, graphite and mint palette.

Rows show observed identity, hotkey counts, take coverage and memberships. Expansion exposes individual hotkeys for navigation and explicit comparison; selections keep the chosen key and operator name visible. Phone and tablet controls use one filter sheet, expanded rows fit long addresses, and the comparison action stays reachable while scrolling.

Supported search/filter/sort URL state, complete CSV export, stable operator IDs and crawlable detail links are retained. Unsupported saved balance filters get a clearable notice. Balance, return and concentration fields remain unavailable pending canonical ingestion; partial take coverage is carried into exports, and the page uses the original observation timestamp. The existing section anchors and deferred permit-cost view remain available.

Closes #12063
Refs #12012, #12013, #12014, #12015, #12016, #12022, #11976

This is the focused directory delivery under #12022. The data-dependent profiles in #11976 remain open. The implementation is confined to apps/ui; API and shared UI-kit contracts are unchanged.

Validation

• 2,411 UI unit tests and all 634 browser checks passed; 19 focused interaction checks include CSV coverage, URL state, source timestamps, column customization, explicit comparison, long identities and touch controls.
• Production Worker build, lint, formatting, type checking, unused module/export checks, SSR content isolation, public-safety scan and diff checks passed.
• SSR HTML fell from 233.51 to 226.46 KiB within the unchanged 245 KiB budget, retaining 50 unique validator links. The lazy route entry grew from 3,414 to 4,681 gzip bytes.
• Initial client static-import closure is checked against the unchanged 400 KiB gzip budget; docs/news retain their independent 70 KiB limits.

Visual evidence

Before: ccbfeafdd10745502173796fbfa3dc7942b8c39a. After: 8e8747f42c45bcaf35c29ca41cfbde62f0c50b6c. The intervening main change touches backend files; baseline UI, packages and lockfile are identical. Captures use separate local production Worker builds, the same recorded API responses, explicit themes and loaded fonts. They establish local rendering and interaction behavior, not production data freshness or a measured field improvement.

Mobile comparison interaction

The recording shows filtering, a real document swipe, expansion, selecting two exact keys, removing one and clearing the selection. The document advances 225px while the nested table scroll stays at zero. Touch removal and action targets are 44px with non-overlapping hit areas; desktop controls retain their compact dimensions.
