chore(ui): UI fixes

[siddhant-galileo]

What Changed

URL-Based Search & Navigation

• Added useQueryParam hook to sync search state with URL query parameters
• Created reusable SearchInput component with clear button and URL sync
• Implemented server-side search for agents and controls with debouncing
• Search state persists in URL (shareable links, browser back/forward support)
• Control Store modal clears search query param on close
• "Used by" links in Control Store navigate to agent detail with control name filter in URL

Sticky Table Headers

• All tables now have sticky headers that remain visible while scrolling
• Applied to: agents overview, control store, add control modal, and agent detail controls tab
• Removed ScrollArea wrappers in favor of table's native scrolling with maxHeight prop

Monitoring Page Improvements

• Upgraded to Jupiter DS v0.0.6 and replaced date picker with TimeRangeSwitch component
• Renamed "Stats" tab to "Monitoring" and agent-stats.tsx to agents-monitoring.tsx
• Improved time range selection UX with segment buttons and dropdown menu

Code Quality & Refactoring

• Refactored all evaluator forms (JSON, List, Luna2, Regex, SQL) for better maintainability
• Created reusable LabelWithTooltip and StepNameInput components
• Improved control definition form structure and validation
• Added infinite scroll hooks (useInfiniteScroll, useControlsInfinite, useAgentsInfinite)
• Server-side search implementation for agents and controls lists

Technical Updates

• Added webpack configuration to handle CSS imports from Jupiter DS
• Updated dependencies (@rungalileo/jupiter-ds@0.0.6, @emotion/is-prop-valid)
• Added DatesProvider to _app.tsx for Mantine date components
• Fixed TypeScript/lint errors and updated all tests

Testing

✅ All tests passing (84 integration tests, lint, TypeScript)

PR Issues (Prioritized)

High

1. Commented-out code - agent-detail.tsx:2551-2555 and agent-detail.tsx:2514 (// color='violet') - remove before merge

2. Complex DOM querying in control-store (modals/control-store/index.tsx:117-143) - fragile scroll container attachment relies on class name selectors that could break

3. Initial tab redirect causes flash (agent-detail.tsx:83-111) - redirects after render if stats exist, jarring UX

Medium

4. Magic strings for modal/submodal names - "control-store", "create", "add-new", "edit" scattered throughout - use constants

5. Inconsistent close behavior (use-modal-route.ts:98-121) - closeSubmodal from "create" goes to "add-new", but from other submodals closes entirely - may confuse users

6. Missing dep in useEffect (agent-detail.tsx:147-156) - selectedControl not in dependency array, potential stale closure

Low

7. Unused destructured variables (use-modal-route.ts:99) - _evaluator and _controlId extracted but unused, could simplify

8. No tests for useModalRoute - new hook with navigation logic has no test coverage
