Subject: [PATCH] Remove ports-disabled modifier from public games (#4464)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary
Removes the `isPortsDisabled` ticket from `SPECIAL_MODIFIER_POOL` in
`src/server/MapPlaylist.ts`, so the "ports disabled" modifier can no
longer be randomly selected for public games.

The reasoning is that many games with disabled ports were filling up
very slowly or not at all (one game I saw had 3 players after 2 minutes)

## Notes
- Private/custom lobbies are unaffected — the modifier itself still
exists (type, schema, client UI), it's just no longer in the public
auto-selection pool.
- The now-unreachable public-game handling for `isPortsDisabled` (the
`FULL_LAND_MAPS` exclusion and the `disabledUnits` branch) is left in
place to keep the change surgical; it simply never triggers for public
games now.
