feat: always show Recreate Tunnel button for web instances

Show the Recreate Tunnel button on all active web-enabled session cards
(instead of only when tunnel_status is unreachable) so users can manually
trigger tunnel recreation at any time. Also adds it to the mobile action sheet.

Quality gates: eslint clean, tsc clean
