An empty mailbox can satisfy an immediate count assertion before an asynchronous notification arrives, hiding unwanted email delivery. Add a bounded observation step using the existing Inbucket helper. Check throughout the observation period and fail when the count differs.
Email notifications can reach disabled users because GetUser does not apply the configured LDAP filters for disabled users. Grouped emails also use the recipient address stored when the events were queued. Look up the recipient again through GetUserByClaim before delivery. This lookup applies the LDAP filters and uses the existing lookup cache. Recheck the global notification setting and use the returned email address. Skip unavailable recipients and log lookup failures without stopping delivery to other recipients. ScienceMesh invitations use the recipient email address from the event without looking up the recipient. Test the internal notification handlers and daily and weekly grouped emails with active users, unavailable recipients, and lookup failures. Related: opencloud-eu#3513
The earlier notification fixes removed these expected failures from the POSIX list but left the two email cases in the decomposed list. Both scenarios pass on the unpatched source base, so the acceptance runner rejects them as unexpected successes. Match the decomposed email expectations to POSIX. Keep the separate in-app notification entry, which the email tests do not cover. Related: opencloud-eu#3257
The existing email scenarios do not check delivery after a user is disabled. An immediate empty-mailbox assertion can also miss email that arrives asynchronously. Extend the existing email feature to cover direct and group shares with cold and expired lookup caches, daily and weekly grouped emails, and file-share removal. Check that active users still receive email and observe disabled recipients' mailbox counts for a bounded period. Use a Graph mention step to check active delivery and the existing API rejection of disabled recipients. The unit tests separately check that events are queued before the recipient is disabled.

Description
Skip notification emails to users disabled through OpenCloud's user management. This covers share notifications to direct recipients and group members, mentions, and daily or weekly grouped emails, including events stored before disablement.

Motivation and Context
The check uses
GetUserByClaimbefore sending becauseGetUserdoes not exclude disabled LDAP users.An existing LDAP lookup cache entry can delay suppression until it expires (10 seconds by default). Disabling a user only in an external identity provider is outside this change.
ScienceMesh invitations use an email address without requiring an OpenCloud user, so they skip the recipient lookup.
Lookup errors skip the recipient. Grouped-email events are still removed before delivery and are not retried after a later lookup or SMTP failure.
