docs: purge stale fabb3421 narrative — Mail.Send already lives in the 365 app suite

Mail.Send is NOT an open decision or a 'blocked' item: the Exchange Operator
tier (b43e7342) already holds Graph Mail.Send + Mail.ReadWrite +
MailboxSettings.ReadWrite (the suite's IR victim-notification mail path).
/mailbox (ACG own-mail) separately uses the dedicated ComputerGuru Mailbox app
1873b1b0. The deleted fabb3421/Claude-MSP-Access app is now referenced only as
DELETED/do-not-use across all live surfaces.

Corrected: remediation-tool gotchas.md (removed 'suite has no mail scopes /
mailbox BLOCKED / decision-not-executed'), commands/mailbox.md (header +
Attribution no longer name the deleted app as active), feedback memory
(promoted 'suite has Mail.Send — settled' to a headline), breach-report
template, .grok mirrors, credentials.md, CATALOG_SHARED_DATA.md, and wiki
(internal-infrastructure, glaztech, dataforth). Removed dead plaintext secret
for the deleted app from CATALOG_SHARED_DATA.md.

Fix: write payload_json to a RELATIVE ./file and use -F 'payload_json=<./file;type=application/json' + -F 'files[N]=@path'. discord-dm.sh is text-only; consider adding an --attach flag.
