* feat(landing): add Contact Sales page and inquiry endpoint (MUL-2493)
Adds a public `/contact-sales` marketing page with a needs-discovery form
modelled on the design reference attached to MUL-2493 — first/last name,
business email (with free-provider rejection), company name + size,
country/region, intended use case, and a free-text goals field, plus the
two consent checkboxes from the reference.
Submissions hit a new public `POST /api/contact-sales` endpoint with
per-IP rate limiting (Redis-backed via the existing RateLimit middleware,
configurable through `RATE_LIMIT_CONTACT_SALES`) and a per-email hourly
cap so a single business address can't be used as a flood channel after
one valid pass. The inquiry is stored in a new `contact_sales_inquiry`
table; analytics fires a `contact_sales_submitted` PostHog event with
only the closed-enum dimensions (size, country, use case) — the free-text
goals stay in the DB and are never broadcast.
The page is linked from the landing header (md+) and the footer's Company
column, in both English and Simplified Chinese. The reserved-slug list is
updated so a workspace named `contact-sales` can't shadow the route.

* fix(landing): canonicalize business email and tighten contact-sales form (MUL-2493)
- Parse the submitted email with net/mail and run the free-email
block-list against the canonical addr.Address, so a display-name
form like `Ada <ada@gmail.com>` can no longer slip past the gate
(the raw string had domain `gmail.com>`, which wasn't blocked).
Adds regression tests covering the display-name bypass and the
canonicalization helper.
- Drop noValidate from the contact-sales form so the browser's
native required / email / select checks fire before submit;
the JS-side free-email warning still runs as a UX guard.
- Update success copy ("respond within three business days") in
EN and ZH plus the page metadata.
