/me's accessible_workspaces query gains a device_count field via a
correlated subquery on workspaces.id - WHERE workspace_id = w.id
strictly excludes the unclaimed pair-pool (workspace_id IS NULL fails
equality). Added to both query branches (platform_admin LEFT JOIN and
regular INNER JOIN); microseconds per row at current scale (~37 rows
worst case), not optimizing.
Frontend appends the count to the muted org-name line with a middle-dot
separator: 'Acme Studios . 2 devices'. Singular/plural respected via the
existing tn() helper convention; 'No devices' for empty workspaces. New
formatResourceCount(n, keyBase, zeroKey) helper is generic so the same
shape can wire users/playlists/schedules counts later without refactor.
New i18n keys: switcher.devices_count_one, switcher.devices_count_other,
switcher.no_devices. Added to en.js only; other locales fall back to en
via the existing lookup chain (verified in i18n.js:19).
API smoke verified: switcher-test sees Studio A=2, Field Crew=2;
dw5304 (platform_admin) sees all 37 workspaces with their device counts
varying 0-4; single-workspace zero-device user (geoff.case) sees 0.
