v1.3.2 — Themed list panels, tofu glyphs removed, layout polish

Fixed

• The SSID and saved-network lists stayed stock white in every colour scheme.
  lv_list is not an lv_obj subclass the theme hook was matching, so it kept
  the default theme's card background — a bright white panel on, say, Red Neon.
  List rows are now flat with a themed separator, and the selected row uses the
  scheme's accent.
• 54 characters in on-screen labels were outside Montserrat's ASCII range and
  rendered as tofu boxes: 29 em dashes (—), 24 bullets (•, the password
  mask on the saved-network detail screen was a row of empty squares) and one
  multiplication sign. Serial-log strings keep theirs — those render in a
  terminal, not in Montserrat.
• The mic-sensitivity readout wrapped to two lines: "-38.0 dBV" measures about
  63 px at Montserrat 14 and the value cell was 64.

Changed

• .gitignore now covers the " 2"/" 3"-suffixed duplicates a sync client
  keeps creating in this working copy, so they cannot be committed by accident.
