fix: Show result count in grep mode status line (#481)

Display match count in grep status line alongside mode indicator.
Format: "<S-Tab> plain │ results: N" (multi-mode) or "results: N" (single-mode).

Modified update_status() in lua/fff/picker_ui.lua to:
- Include pagination.total_matched in grep mode status
- Show both mode indicator and result count when multiple modes configured
- Show only result count when single mode configured
- Use separator " │ " between mode and count

Fixes file picker status display unchanged.
