fix(menu): release Left from kb-move-char-back before binding it to Back

rofi hard-fails on a duplicate keybinding and reports it in a GUI error
dialog, not stderr — so 05bab55's Left=Back killed every menu entry
point on a real session while passing all stubbed tests. Rebind
kb-move-char-back to Control+b in both rofi_menu copies (menu + vpn).

V3 on the migrated T14s: error dialog reproduced with old flags, menu
renders with fixed flags. Journal + two PROPOSED pitches (EasyEffects 8
tray icon, parallel fingerprint/password PAM).

+- **EasyEffects 8 tray icon breaks bar aesthetics** (2026-07-11, T14s
+  V3) — EasyEffects 8 (Qt SNI rewrite) publishes IconName
+  `com.github.wwmm.easyeffects`, which resolves to Papirus's full-color
+  blue icon in Waybar's tray; EE 7 showed a symbolic glyph that matched
+  the monochrome bar. Options: ship a monochrome override SVG shadowing
+  the id in `$XDG_DATA_HOME/icons/<icon-theme>/…` (must follow the
+  theme's icon set per THEME-DESIGN), or upstream a `-symbolic`
+  IconName. Cost: small for a single-icon override, but it's per-icon
+  whack-a-mole — worth deciding a general "tray icon parity" policy
+  (nm-applet/udiskie currently pass only by luck of their icon sets).
+
+- **Fingerprint *or* password, in parallel** (2026-07-11, Bernardo) —
+  `fingerprint.pam` gives pam_fprintd's sequential UX: sudo waits on
+  the reader, password only after failure/timeout. Bernardo wants
+  either factor accepted at the same prompt (type the password *or*
+  touch the sensor, whichever comes first). Stock PAM can't express
+  this; needs a parallel-conversation module (e.g. `pam-any`, not in
+  nixpkgs — would be a new package + `fingerprint.pam = "any"` mode).
+  Cost: medium (package + PAM wiring + careful lockout testing on real
+  hardware). Security note: keep sudo fallback sane if fprintd hangs.
