feat: Add dump commands, graphical layout visualizer, and visualizer improvements

[WeekendSuperhero]

Summary 🎯

Adds powerful debugging tools: CLI dump subcommands for layout/palettes/info, interactive graphical panel visualizer (Macroquad window: rotate, click-to-flash panels), and TUI visualizer upgrades (palette switching, axis/sort controls).

Key improvements: Loopback audio detection (BlackHole/etc.), device auto-power-on, global orientation-aware sorting, instant transitions (transition_time: -1).

New Features 🚀

CLI dump (standalone, no TUI)

Command	What it does
audiotui dump layout	Panel table (ID/shape/X/Y/O/side) + raw /panelLayout/layout JSON
audiotui dump palettes	All built-in palettes w/ hues
audiotui dump info	Full /api/v1/ device info (no auth needed)
audiotui dump layout-graphical	Macroquad window: Visual layout w/ rotation, click panels to flash! (ESC=close)

TUI Visualizer (V key) ✨

• 1-0: Switch palettes (shows first 10)
• A: Toggle X/Y axis
• P/S: Primary/secondary sort (Asc/Desc)
• Live status display

Other

• Audio: Prefers loopback (BlackHole/Monitor) > mic (w/ install hint)
• Device: Auto on + brightness=100 if needed
• Config: transition_time: i16 (-1=instant)
• Sorting: Respects global orientation

(Graphical viz shows triangles=red, squares=green, hex= blue, etc. Controllers= yellow trapezoids)

• Layout table: Clean bounds + stats
• Macroquad: Clickable, rotatable panels w/ flashing!

Breaking Changes ⚠️

• transition_time: u16 → i16 (-1=instant/start-frame)
• New subcommands: audiotui dump ...
