fix(ui-components): reduce empty search state padding

[shivxmsharma]

Description

The search modal shows a large blank space below the "No results found" message when a search returns no results.

The root cause was in .noResultsWrapper inside Search/Results/Empty:

• h-full — stretched the wrapper to the full parent height, expanding the empty area
• pb-31 (7.75rem / 124px) — excessive bottom padding originally used as a visual centering trick for full-screen mobile, but creates a large visible blank gap on desktop

Fix: Remove h-full and reduce pb-31 → pb-6 (1.5rem). The wrapper now sizes to its content and the modal stays compact.

Validation

1. Open the search modal (Ctrl+K)
2. Type a query that returns no results
3. The "No results found for X" message appears without the large blank space below it
4. Modal still looks correct when results are present
5. Both light and dark mode unaffected
