* fix: database is locked
The option "_journal_mode=WAL" is currently *not* being applied when
provided in the DSN.
This issue affects only new memos installations, not older ones where
the database journal was properly set to WAL mode by the previous sqlite
library go-sqlite3.
modernc.org/sqlite DSN parsing is different from go-sqlite3. It requires
the `_pragma=` prefix and even some options order matter.
