fix(mental-health): crisis card no longer sends AT/CH users DE-only numbers

The PHQ-9 item-9 crisis card routed every "de" locale to the Germany-only
TelefonSeelsorge freephone lines. Those numbers don't connect from Austria
or Switzerland, so a Swiss or Austrian user in crisis was shown dead numbers
first on the one surface where that costs the most.

Add dedicated Austria (Telefonseelsorge 142) and Switzerland (Die
Dargebotene Hand 143) resource sets. `User.locale` only ever stores a bare
short code today, so an unqualified "de" now resolves to a combined
DE/AT/CH set (112 first, then every country's own line) instead of
defaulting to Germany; a region-qualified tag resolves to the exact country
when one is available.
