shim: shorten subtitle stream labels in detail dropdowns

Browse source 
Stock Jellyfin renders subtitle stream entries as
"<lang> - <CODEC> - (External|Internal|Embedded)[ - flag]". For ARRFLIX,
which has at most one subtitle format per language, the codec and source
suffix are noise. Add a small JS shim to web-overrides/index.html that
matches that exact shape and collapses the label to "<lang>" (with
"(Forced)" / "(SDH)" / "(Hearing Impaired)" if those flags are
present; "Default" is dropped since it's redundant when there's only one
stream of that language).

Audio labels like "5.1Ch Surround Sound - English - AAC - Stereo - Default"
have a different number of segments and don't match, so they pass through
untouched.

The shim runs after DOMContentLoaded and re-walks any nodes added later
via MutationObserver (covers actionsheet dropdowns that mount lazily).

Bracketed by /* SUB-LABEL-SHIM-BEGIN */ and /* SUB-LABEL-SHIM-END */
markers; bin/revert-sub-label-shim.sh deletes between the markers in one
sed pass and saves a timestamped backup. No container restart needed
(index.html is bind-mounted).
