favicon hijack + tonemap fix shipped to prod

Browse source 
Favicon: prod's older lockFavicon() shim was clobbering our injected
A-logo <link> tags every head mutation. Tag our links with
data-arrflix-icon="A" + add a hijack IIFE that re-pins the A URL on
matching tags AND removes any other large data:image/png link tags.

Tonemap: encoding.xml flipped EnableTonemapping false to true on dev
+ prod (server-side, not in repo). Doc 21 documented this fix
2026-05-08; prod was still grey-washing HDR10 sources because
setparams was relabeling PQ pixels as bt709 without zscale + tonemap
conversion. API now reports EnableTonemapping=True. Next HDR10
transcode gets the proper zscale -> tonemap -> format ffmpeg chain.

Both verified on dev first then promoted. Prod overlay md5 c6c85076
to 364cc890. dev and prod overlay byte-identical.
