email leaves the platform for plugins/email

the sidecar, the router, the table, the screens and the account manager are
gone from src/ entirely - deleted, not commented, because a commented mount is
what assertPermissionTotality cannot see.

three reverse imports had to go first, and they are what decided the boundary.
core may not import a plugin's queries, and one of these had already proved
why: getEmailAccounts was awaited at the top level of the agent sidecar, so
when the table went away on 2026-08-13 the rejection took officer-agent into a
pm2 restart loop with every live chat session inside it (fbb6d6c7).

both survivors now read the DISK instead. findEmailAccountName() in
data-path.ts picks the newest emails.db under an account's email_accounts/
directory - no import, no query, and nothing to throw when the plugin is not
installed. the layout was already the platform's, so this costs no coupling.
the agent keeps its email_db tool and an email-context chat still opens in the
right mailbox.

the google oauth callback no longer appends /email to the dock: a plugin's
route is the plugin's business.

app-store/catalogue.ts entry deleted, and that is the whole point rather than
tidying. permissionAvailability derives from sidecar_installs and a plugin only
ever gets a plugin_installs row, so a leftover entry makes the permission
permanently unavailable - denied route, no dock tile - on a machine where the
plugin is installed and healthy. it has bitten headscale and nearly music.

two app-store tests used email as their config-only fixture; repointed at
notify, which is the same shape.

google-auth stays in core and the plugin imports it via @@/. that direction is
allowed and google-auth knows nothing about mail.
