jcoffey-dev 2d8728793c Don't let a group's members share its mailboxes on
ci / github (pull_request) Skipped
ci / fork-checks (pull_request) Failing after 1m16s
ci / build (pull_request) Canceled after 5m6s
A group's members reach its mailbox through membership, which counts
as owning the account, so every ACL check was skipped: on a scratch
server a member gave an outsider read access to the group's Inbox with
one Mailbox/set shareWith, with no administrator involved and nothing
audited. Who is in a group is an administrator's decision.

AccessToken::is_group_member_only names that case (in the account
only through a group, without Impersonate). For such a member:

- Mailbox/set with a shareWith change, on create or update, is
  refused as forbidden;
- IMAP SETACL and DELETEACL answer NO [NOPERM];
- myRights reports mayShare false, and MYRIGHTS leaves out "a";
  every other right stays.

Administrators and the account itself are unchanged. The JMAP ACL
test's group section now checks all three for a member and that the
outsider still has nothing (specs/multi-account.md, MA-D0, G1).

jmap_tests and imap_tests pass (RocksDB). The IMAP refusal has no test
of its own yet; imap_tests passing shows the rest is unchanged.

jcoffey-dev 6a53d47106 Mark the files this fork changed (AGPL section 5(a))
The AGPL asks a modified version to carry prominent notices saying it was
modified, and giving a date. Publishing the source is the conveyance that
asks for it, so it wants doing before the repository is public rather than
at the release.

Every upstream file the fork changed now says so in its header, beneath the
notice it came with: 164 files, found by diffing against the upstream
snapshot branch rather than by guessing, so the list is what actually
differs. Files the fork wrote itself already carry their own copyright and
need nothing. Upstream's notices are untouched, which its licence requires
and which was already true.

The README says the same thing in prose, since the obligation is on the
work as a whole and not only its Rust files.

Builds unchanged: the server and the test binary both compile.

jcoffey-dev bcf4a49325 Multi-tenancy: sharing grants stay within the owner's tenant (MT-1, MT-3)
JMAP shareWith refuses a grantee outside the owner's tenant, or missing, with
invalidForeignKey naming the account. WebDAV ACL answers AllowedPrincipal and
IMAP SETACL answers as for an unknown account.
