Support moving the cursor left and right within the Filter/Search bar text input so users can edit text in the middle of the input without having to delete everything first.

Added filter_cursor and search_cursor (byte-offset) fields to AppState. Updated handle_filter_input_event and handle_search_input_event to handle Left/Right (move one char), Home/End (jump to start/end), cursor-aware Backspace (delete char before cursor), and cursor-aware Char insertion (insert at cursor). Updated render_filter_bar and render_search_bar to split input at cursor and show a highlighted block cursor glyph at the correct mid-text position. Updated help modal to document the new bindings. 23 new tests added; all 297 pass.
