The coach option chips rendered raw 'labUi.coachForm.…' keys because the 29
per-option translation keys were referenced dynamically (t(option.key)) and had
never been added — the literal-only i18n guard missed them. Add every option
key (EN/ES) and extend scripts/check-i18n.mjs to also scan data tables for
key/titleKey/labelKey/badgeKey entries so this can't recur.
Also fix the chip layout: the global mobile 'button { min-height:44px }' rule
turned every chip into a 44px slab; add min-h-0 to the coach option chips,
language chips, Lab facet chips and Lab active-filter chips.
Remaining nice-to-haves:
- Structured rate: rate_amount + rate_currency (sats/USD/EUR/GBP) + rate_unit
(hour/session/half-day/day/camp), rendered on the detail page; legacy
freeform 'rate' still shows and acts as an optional note.
- Section the long coach form with a FormSection divider.
- Restyle the coach identity block from a red error-looking box to a neutral
avatar card.
