fix(ux): pass-3 — yacht/company headers, reminder filters wrap, client tab counts

Five small fixes from the third audit pass on previously-unchecked surfaces:

Yacht detail header (mobile):
  - Stack the action cluster (Edit / Transfer / Archive) below the title
    block on phone widths. Previously the three buttons crowded the right
    side enough to truncate the status pill to "A..." and force the owner
    name to wrap to two lines. Same fix that landed for berth / client /
    company headers.

Company detail header (mobile):
  - Same mobile stacking fix; legal-name + Tax-ID metadata no longer
    wraps awkwardly.

Company detail Incorporation Date (all viewports):
  - Strip the time portion of the ISO timestamp before passing to the
    inline editor. Previously rendered the raw "2019-03-14T00:00:00.000Z"
    Postgres-serialized form. Now reads "2019-03-14" and round-trips
    through the YYYY-MM-DD inline editor cleanly.

Reminders list filter row:
  - Allow flex-wrap on the My/All tabs + status filter + priority filter
    cluster. At 390px, the priority filter dropdown was being pushed off
    the right edge of the screen.

Client detail tab counts:
  - Add interestCount + noteCount to getClientById response, surface as
    badges on the Interests + Notes tabs. Brings them into parity with
    Yachts/Companies/Reservations/Addresses which already showed counts;
    Files + Activity are still stubs and don't get a count yet.

Verification: 0 tsc errors, 926/926 vitest passing, lint clean.

Out of scope (deferred):
  - Residential clients / interests pages still render plain HTML tables
    on phone widths (header columns clip at the right edge). Needs the
    DataView card-on-mobile treatment that the main /clients and
    /interests pages already have. Substantial separate work.
  - Phone contacts in the legacy seed have value set but valueE164 NULL,
    so InlinePhoneField shows "—" even though metadata is technically
    populated. Fix is a one-time backfill via libphonenumber-js, not a
    UI change.
