Move the board out to the service every game shares

The leaderboard started in this repository because when it was written there
was one game. It was already being treated as shared -- games.jcoffey.dev
calls it "the shared leaderboard" in its compose file and nginx proxies it at
a site-wide /api/ rather than under /lemonade/ -- but it was still this game's
code, and the second game would have meant a second container, a second volume
and a second database to back up for every game after that.

It lives in https://github.com/Coffey-Labs/games-scores now, which is its own
repository rather than either game's. A shared board belongs to no game, and
leaving it here would have made every future game depend on the lemonade stand
for its leaderboard.

What changes here is smaller than the diff suggests. server/ goes, and with it
scripts/dev-all.mjs and two package scripts. The client names the game on every
call and is otherwise untouched: rows still come back as assets, days, glasses
and broke, because the shared service hands each game its own field names back.

Nothing about the deployed board moves. The volume keeps its name, the rows are
migrated in place on first boot, and the original table is kept alongside as
scores_lemonade_v1 rather than dropped -- it is the only copy of a board real
people are on. Bundles already in browsers keep working too: a post with no
game at all is treated as this one, deliberately, until this build has been out
long enough that nobody is running the old one.

Build clean.
