fix(tests): fix searchEmails FTS5 query, chaos monkey timeout, and format

_toFtsQuery was stripping non-word chars within tokens rather than
splitting on them — 'searchable-{timestamp}' became 'searchable{timestamp}*'
but FTS5 tokenizes on hyphens so the merged token never matched. Split on
non-word chars so each FTS token is queried separately.

chaos_monkey_test had no timeout annotation, hitting Dart's 30s default
for a test that needs ~60s with 30 SMTP/IMAP rounds. Added Timeout.none.

Also applied dart format to files from the merged main commit (#512) that
were committed without running the formatter.
