refactor(ui): delete dead button code (buttons.h + ApplyTactile)

Browse Source 
UI-standardization audit found two dead, contradictory "how to draw a button"
surfaces with zero call sites:
- src/ui/material/components/buttons.h (353 lines: TextButton/Outlined/Contained/
  Button(spec)/IconButton/FAB) — included by 3 mining files but never used.
- ApplyTactile (draw_helpers.h) — a retrofit-tactile-onto-plain-button wrapper,
  never called.
Remove the file, the 3 dead includes, and ApplyTactile. TactileButton/StyledButton
remain the canonical button helpers. No behavior change.
