Two duplications surfaced by a framework-consistency pass:
- KeyboardWidget applied the a-z shift-uppercase at five draw/commit sites
with an inline `if (caps && ch >= 'a' && ch <= 'z')`. Fold them into one
`kbApplyCaps(ch, caps)` helper.
- The favourites grid drew the empty "+" tile from two branches (the gone-slot
prune and the always-empty slot). Route both through a single `has_contact`
flag so the "+" and the trailing selection-colour reset each live at one site.
No behaviour change. Builds green: WioTrackerL1_companion_solo_dual.
