fix(data-list): lift the selection bar above the mobile nav and fix tap targets

The page-scoped selection bar sat sticky bottom-2, behind the fixed
64px mobile bottom-nav, so the destructive Delete (N) button was
unreachable on phones and ignored the iOS home-indicator inset. Lift
it to clear the nav band + safe area on mobile and drop back to
bottom-4 at sm+ where the nav is hidden.

The per-row select checkbox wrapped a Radix checkbox (a 16px button)
in a 44px label; a label does not forward taps to a button, so the
effective target failed WCAG 2.5.5. Make the 44px area a single
button that owns the toggle, with the checkbox a pointer-events-none
controlled visual, avoiding any double-toggle.

Bring the mood pagination buttons to the 44px target used by the
measurements list. Add (sort: Desc) to the two source-filter indexes
so the schema matches the DESC migration SQL; schema-fidelity only,
no new migration.
