🐛 Fix the defects the review of the branch commands found
The source notes on files_branch.clj listed 32 review findings. This
commit fixes the 21 that are defects of the code; each fix carries a
regression test that failed before it and passes after.

Concurrency: merge, update from main, rename, archive and delete now
re-read the branch row under the advisory lock and work off that row,
so a concurrent merge or update can no longer leave a ten-year base
pin behind or release a superseded base twice. Delete and archive take
the branch file lock, create and reopen of a pull request refuse a
branch that a concurrent merge closed, and create checks the branch
quota under the lock. Merge, update and delete publish their msgbus
messages only after the transaction commits.

Merge, update and materialize re-validate after the repair: merge and
update refuse a result that stays invalid, materialize logs it. The
change log row carries the repair changes, and the three paths drop
the cached file summary under :redis-cache.

Contracts: a :conflict refusal answers 409 instead of 500, resolution
values must be :main or :branch, and update from main accepts the
expected-main-revn token the frontend now sends from a loaded diff.

Smaller fixes: create refuses a blank name, writes no file_data row,
and a rename reaches the branch file's own name. Deleting a kept
merged branch keeps its merged status. get-branch-diff reports the
creation time of the current base snapshot. Rename, archive and delete
report their duration and outcome. An image used only by a library
colour is copied into the target file. Dead fallbacks and dead
deleted-at checks are gone.
