Make escape key clear filters one layer at a time (#111)

## Summary
- When both hide-addressed and project filter are active, escape now
clears only the project filter first
- Pressing escape again clears the hide-addressed filter
- Fixes visual flash where "No jobs matching filters" briefly appeared
while loading after clearing a filter - now shows "Loading..." instead

## Test plan
- [x] Enable hide-addressed filter (`h`)
- [x] Apply a project filter (`f` → select repo)
- [x] Press escape → verify only project filter clears, hide-addressed
remains active
- [x] Press escape again → verify hide-addressed clears
- [x] Verify no "No jobs matching filters" flash during filter clearing
