feat(website): book an intro call after partner application (#21343)

## What

After a partner submits the application wizard, the success screen now
offers an inline Cal.com booking widget so they can book an intro call
on the spot — keeping the partner process high-touch.

- Inline Cal.com embed on the application success step, prefilled with
the applicant's name/email (company in the notes)
- Wide `month_view` layout; the success modal widens to ~960px (the
4-step form and mobile are unchanged)
- Event-type-details panel hidden via `cal('ui', { hideEventTypeDetails:
true })` so it's just calendar + times, on its own `partner-intro` Cal
namespace (isolated from the ContactCal embed)
- "I'll book later" escape hatch; backend / submission path untouched

## Why

The warmest moment is right after someone opts in. Today the success
screen only shows a Close button — this turns that moment into a
scheduled conversation.

## How

- `PartnerIntroCalEmbed` — thin wrapper over `@calcom/embed-react`
(already a dependency), reusing the existing `ContactCal` embed pattern
- `buildPartnerIntroPrefill` — pure mapping of applicant fields → Cal
prefill
- `PartnerApplicationSuccess` — presentational success view (heading +
subtitle + embed + dismiss)
- The wizard reports submitted-state up (`onSubmittedChange`) so the
modal widens only on the booking step
- New Lingui copy + regenerated catalogs (en/es/fr)

## Test plan

- `npx jest PartnerApplication` — green (prefill mapping, embed
link/layout/prefill, success view)
- `npx nx typecheck twenty-website` — clean
- `npx oxlint -c .oxlintrc.json` / `npx oxfmt --check` — clean
- Manual: submit the wizard → success step shows the wide booking
calendar, prefilled, dark theme, no event-details panel; "I'll book
later" closes the modal

## Notes

- Frontend only — no backend, schema, or submission-path change
- Cal link `rashad-twenty/partner-intro` lives as a constant in
`config.ts`
- Branch is currently behind `main`; happy to rebase before review
