fix(dark-theme): PlayStateIcon glyph beats .dd-accent-icon; GasLampLit self-colored frame

PlayStateIcon.razor.css adds a .mud-icon-root rule !important so the play chip always shows
navy on moss-green in dark. GasLampLit frame path changed from currentColor to #2A5C4F;
dead nav dark rule removed.

+/* PlayStateIcon is authoritative over its own glyph colour — a surrounding .dd-accent-icon
+   must NOT recolor the play-chip glyph in dark. The consolidation rule is:
+     .dd-accent-icon .mud-icon-button .mud-icon-root  (0,3,0) !important
+   After Blazor scoped-CSS compilation this rule becomes:
+     .deepdrft-theme-dark .icon-container[b-xxx] .mud-icon-button .mud-icon-root  (0,4,0) !important
+   (0,4,0) beats (0,3,0) — wins on specificity; !important parity is irrelevant.
+   Dark only: light already renders the navy glyph via the MudBlazor Color prop. */
