[feat](trx-frontend-http): frequency-ordered z-index and hover-to-front for RDS overlay layers

Browse Source 
Each RDS PS overlay item (position: absolute within the shared #rds-ps-overlay
container) now receives a z-index derived from its channel frequency: items are
sorted by freq_hz ascending so higher-frequency layers sit on top of
lower-frequency ones by default.

Hovering any layer temporarily assigns it the maximum z-index (entry count + 10)
to bring it to the front; mouseleave restores the frequency-derived default
stored in data-default-z.

Also reverts the incorrectly applied vchan picker layer changes from the
previous commit.
