fix(waybar): inhibited notification state reads by shape, not color alone

Item 28 color-only accessibility sweep. Swept every Waybar status
indicator for shape/glyph redundancy: all already carry non-color
distinction (updates shows a count + self-hides; vpn/doctor/nightlight/
recording self-gate; battery/idle/muted are glyph-distinct) except the
swaync notification module — its `inhibited-*` states reused the normal
bells (󰂜/󰂚), so an app-inhibited (suppressed) state was distinguished
from a normal one by color alone.

Route every suppressed state (DND + inhibited) to the bell-off glyph 󰂛
+ @muted, so "notifications are off right now" reads by SHAPE. Applied
to the generated bar and all four whole-swaps (summer-day/night use
their own bell-off glyph; executive-slate/boreal use 󰂛) — parity rule.
Reuses the glyph DND already ships, so no new codepoint / tofu risk.

Verified: V0 (flake check --no-build; 4 jsoncs valid JSON) + V1 (built
homeConfigurations.nomarchy.activationPackage — the built config has
inhibited-* = U+F009B and style.css routes .inhibited-* → @muted).
V3 pending: live inhibited-state render with an app holding an inhibitor
(HARDWARE-QUEUE). MEMORY gains the "status is never color-only" invariant.
