#309: AccountDao no longer uses @Insert(REPLACE). New insertIfAbsent (IGNORE)
+ @Update back a non-destructive upsert, and insertAtEnd updates an existing id
in place (preserving its sortOrder) instead of REPLACE. Re-adding an existing
account id (e.g. re-authing an Outlook account, whose id is the deterministic
outlook:<email>) therefore no longer cascade-deletes its account_settings +
signatures.
#305: normalizeEmailForAccountId always lowercases the domain (mail domains are
case-insensitive), and the whole address for the consumer providers (Gmail,
Yahoo, iCloud, AOL, Outlook). Applied at every id-derivation site
(MailProvider.createAccount, Account.outlook, ManualSetupViewModel) so
differently-cased addresses can't spawn duplicate accounts. The displayed email
keeps the user's casing.
#299: deleteAccount collects the account's message ids and draft attachment URIs
while the rows still exist, deletes the rows (now including the account's
drafts), then deleteRecursively()'s each message's on-disk attachment cache dir
and releases the drafts' now-unreferenced persistable URI grants.
Adds unit tests for id normalization + deleteAccount cleanup and DAO-level
instrumented tests for the non-destructive create/update.
