Curses waits up to 1 second after ESC to distinguish it from escape
sequences (arrow keys, F-keys). Set ESCDELAY=25 before curses.initscr()
so ESC responds near-instantly while still handling escape sequences.

- Reuse a single SQLite connection instead of open/close per query
- Add in-memory cache for frequently accessed data (brands, models,
categories) — 1000x faster on repeated access
- Enable WAL journal mode, 8MB cache, 64MB mmap for faster reads
- Cache terminal size per render cycle to avoid repeated getmaxyx()
- Close DB connection on app exit

Implement TextualRenderer in console/renderers/textual_renderer.py using
the Rich library for a modern dark-themed TUI with blue/cyan accents.
All 18 BaseRenderer methods are implemented: lifecycle (init_screen,
cleanup), primitives (clear, refresh, get_key, get_size), widgets
(draw_header, draw_footer, draw_menu, draw_table, draw_detail,
draw_form, draw_filter_list, draw_comparison, draw_text, draw_box),
and dialogs (show_message, show_input). Keyboard input uses raw
terminal mode via tty/termios with full escape sequence decoding
for arrow keys, F-keys, Page Up/Down, Home/End.
