* fix(stalker): send cmd in the reference MAG wire format

A real MAG sends cmd unencoded and the portal decodes its query exactly
once, so a cmd that already contains percent sequences (%3A tokens,
pre-encoded path segments) must pass through untouched. The previous
encodeURIComponent transport (2c032cd3c, 0.22) double-encoded such cmds
(%3A -> %253A): strict portals and reseller panels that compare cmd
literally, and stock create_link handlers matching the decoded value,
saw a different string than a real STB sends.

The new shared encodeStalkerCmdValue() reproduces the reference wire
bytes: % passes through verbatim, characters the WHATWG URL serializer
keeps raw in a query stay raw (so the bytes survive the axios/new URL
transport unchanged), and everything else is percent-encoded. That
preserves the 0.22 injection protection - &, # (and ; for PHP setups
with a ; argument separator) inside cmd cannot append or truncate query
parameters; they decode back to the original byte server-side.

Both transports now share the format: the Electron query builder is
extracted to buildStalkerRequestUrl() and the web-backend /stalker
proxy appends cmd to the portal URL itself instead of letting axios
turn slashes into %2F (the opposite divergence).

Also unifies the two divergent response-side cmd normalizers: the
cross-portal collection resolver now uses the Stalker store's
normalizeStalkerPlaybackCommand/resolveStalkerPlaybackUrl, so playing
from Favorites/global collections resolves relative (/media/...) and
query-only (?token=...) create_link replies against the portal base
instead of handing the player a bare relative path.

The mock portal's create_link response gains mock-only cmd_received/
query_keys_received diagnostics; a new Electron e2e pins the contract
end-to-end (single decode, injection blocked). Unit corpus tests cover
the encoder, the Electron builder, the web-backend proxy, and the
resolver.

* fix(pwa): sanitize portal URL before appending stalker cmd

A registered portal URL carrying a fragment would swallow the appended
cmd (everything after # is never transmitted), and a trailing bare '?'
produced '??cmd='. Drop the hash and pick the separator from the
sanitized href before appending. Flagged by Greptile/Codex on #1334.

* refactor(pwa): make stalker cmd append visibly query-only for CodeQL

Rebuild the /stalker request URL through the URL object and concatenate
the encoded cmd strictly behind a literal '?', so static analysis can
see the tainted value never reaches host or path (js/request-forgery
alert on the previous separator ternary). Behavior unchanged; the
fragment/bare-'?' regression tests still pin the wire format.

fix stalker

Stalker portals now receive channel commands exactly as a real set-top box sends them: already-encoded parts of a channel's cmd are no longer double-encoded, so strict portals and reseller panels that compare the command literally work again. Playing Stalker channels from Favorites or global collections now also handles portals that answer with relative stream paths.
