JL Cooper MIDI Controller I/O, Focus widget hardware binding, iOS Channel Focus polish

Desktop:
- New dedicated MIDI Controller In port (separate from MIDI In), same CC learn/bind pipeline but never passes notes through; positioned first in the IO column order
- Fixed MIDI In "Not Connected" not persisting across restart (missing save_io_config call)
- Fixed MIDI Out/Transport Out mutual-exclusion incorrectly flagging "Not Connected" as an in-use port
- Renamed "Remote" checkbox to "App" on Fader/Toggle/Transport widgets
- FocusFaderWidget/FocusToggleWidget: new Hardware section (Learn + CC/CH bind) so a physical controller can drive a Channel Focus widget alongside the app/OSC, plus an independent Feedback checkbox that sends translated CC out (for motorized fader / LED sync)
- JL Cooper touch-sense profile ("No Profile" / "MIDI JL Cooper CC Mode") on FaderWidget/FocusFaderWidget: touch channel (value channel - 1, same CC) is filtered out of the value and gates incoming OSC/DAW feedback while touching
- FocusFeedbackWidget: "Custom" checkbox to show a manually-typed static string instead of live OSC feedback, disabling Learn/OSC input and suppressing the iPad broadcast while active
- New daw-config-reaper/ folder with reaper-osc-config-paul-custom.ReaperOSC

iOS:
- New FocusToggleWidget (dedicated Channel Focus toggle, split out of shared ToggleWidget) with colorName-aware darken/border and isMomentary handling — keeps Channel-Focus-only behavior off the regular ToggleWidget
- Arrange mode long-press menu: text alignment (left/center/right) and a 10-color named-palette Text Color picker for TitleWidget/FocusFeedbackWidget, persisted in the saved layout
- FocusFeedbackWidget: Reset Size action, monospaced-digit font fix for timestamp/counter jitter
- New "Cancel Changes" button in Arrange mode — reverts layout/hides/aligns to the state at Arrange-mode entry and restores desktop-side Remote/dest assignments
- Grid line brightness increased for visibility
- Bonjour discovery for desktop auto-connect
