fix: Mute and Min Interesting key codes not properly assigned

[sayden]

Hey,

TourBox Neo user here. Thanks for maintaining this project. I have been happily using these drivers in a variety of applications and recently I wanted to use the TourBox for common tasks so I set up the knob to control the volume of the session but, when I tried to assign the "Mute" function is was not working.

I gave it a try it's now working as intended (and everything else).

But I lack context about the internal workings of the project so feel free to reject the PR or ask me for some change.

Cheers

Thanks for tracking this down — you nailed the root cause. KEY_MIN_INTERESTING was getting written instead of KEY_MUTE, then dropped by config_loader.parse_action because only KEY_MUTE is in the whitelist. The prebuilt reverse-lookup is also a nice cleanup over the per-call e.__dict__ scan.

One change before merging: the "pick the shortest alias" tiebreak works for KEY_MUTE today, but it's a heuristic. For example, code 152 (KEY_COFFEE / KEY_SCREENLOCK) would pick KEY_COFFEE even though KEY_SCREENLOCK is what users would expect, and any future entry added to SPECIAL_KEYS is one alphabetical reshuffle away from re-breaking the same bug.

We already use an explicit preferred-name dict for a similar case in tuxbox/gui/controls_list.py (PREFERRED_NAMES, mapping codes → display labels). Mirroring that pattern here makes the intent explicit and matches config_loader.KEY_NAMES (the parse whitelist) by construction. Suggestion inline.
