Rename medcenter landings and add the revenue calculator

Rename the two medcenter landings to their audience names:
medcenter -> medcenterphysio, medcenterpersonal -> medcenterstart.

Alongside the rename:
- add a RevenueCalculator section to both landings;
- rework the copy and figures in src/data/content.ts;
- simplify the lead form: drop the "cabinet_state" and "profile"
  selects (along with SelectField and the matching fields in
  shared/lead.ts, lead-mapper.ts and amo-check.ts) and make
  company and email optional;
- add the legacy/new static prototypes for both landings;
- add pnpm-lock.yaml to medcenterstart (package-lock.json is still
  there too).

deploy/apps.conf and deploy/README.md still refer to the old
directory names and need a follow-up.
