The SQLite archive files the database target writes are now managed by
internal/archive: file names, rotation, the writer of each target,
pruning, renames, the gzipped JSON export, the idle sweep, and the
lock renames run under, which was Handlers.renameMu. The database
target stays in internal/delivery and writes through archive.Writers;
the engine still closes the writers when it stops, so the stop order
is unchanged. The handlers take the lock, rename and evict through
archive.Archives.
Exported names drop their Archive prefix in the new package. The
tests moved with the code; the two that check a delivery's recorded
attempt stay in delivery.

A database target's rotation setting (none, monthly, daily or hourly) puts the UTC period of each event's receive time in its archive file name, so each file holds exactly its period's events. It is on the new webhook page and both target forms, and shown in the target list. Renames move every one of a target's files and move them all back if one fails. The sweep prunes one file at a time under the target's lock and deletes a rotated file it leaves empty. Download opens one file at a time, oldest period first, finding each again under the target's current name. The target list names the current file and totals all of them.

Each database target on the webhook page has a Download button that streams its archive as gzipped JSON, archive-WEBHOOKNAME-TARGETNAME-TIME.json.gz, with names made safe by delivery.ArchiveFileName's function. The export reads one consistent snapshot through one cursor in a read-only transaction, so archive writes carry on, and holds the rename lock only while it reads the stored names and opens the file. It extends its write deadline as it writes, so a large archive downloads for as long as the client reads; a failure after the response has started aborts the connection so the browser marks the download failed. The request limit is now the service's own middleware, which no longer writes a 504 over a response already started.
