fix(seasons): supply the FUT web-file base so Seasons stops failing

Entering single-player Seasons showed "There was a problem communicating with
the FIFA Ultimate Team Servers". The deployed trace caught the whole chain:

  SEASON_CALL: LoadOfflineSeasons_asyncimpl(0x57560)
  SEASONS_WEBFILE_URL: url="packs/loc/storepackdescriptions.en_us.xml"
  SEASONS_STAGE1: status(+0x1c)=999 -> CACHE_PACKNAMES_FAILED
  SEASONS_LOAD_CALLBACK: final kind=ERROR result="CACHE_PACKNAMES_FAILED"

Not a server fault: no /season/* request is ever made. The client's
RS4::ServerSettings CDN base is EMPTY in the emulator, so the pack-names web
file is requested as a BARE relative path and 999s, and Seasons aborts on that
prerequisite.

Ports the base-supply rewriter from wip/seasons/base-supply-veh onto the
deployed lineage (that branch forked before the TLS work and cannot be rebased),
taking only the URL supply: absolute urls pass through untouched, and the
success-forcing CACHE_PACKNAMES bypass is deliberately NOT taken — masking the
failure would hide whether the supply actually worked.

Corrects the port while porting: the branch hardcoded 8110, where nothing
listens. The content server is POW (`pow_server.py`, kind "content") on 8085 —
the port Blaze already advertises to the client as its content host. Verified
live: GET http://10.10.0.120:8085/fut/packs/loc/storepackdescriptions.en_us.xml
returns 200 with a 180-byte XLIFF document. `default_ports::FUT_CONTENT` is now
8085 and the base is still derived from openfut.cfg, so no address is compiled
in (confirmed absent from the artifact).

Artifact keeps the roster TLS gate patch (11 fifa17_tls markers) and the kit
trace alongside the new base supply.
