test(e2e): exhaustive click-through suite + destructive narrow tests

PR 14: adds a tier-3.5 Playwright pass that opens every refactored page,
clicks every visible button/link/role=button, and asserts no console
errors, no app-side network 4xx/5xx, and no click-time exceptions.

Helper:
- tests/helpers/click-everything.ts — shared `clickEverythingOnPage`
  with default skips for destructive selectors (archive, delete,
  transfer, sign-out), auto-closing of dialogs, and return-to-start
  after navigation.

Exhaustive specs (tests/e2e/exhaustive/):
- 01-yachts: list + detail + transfer dialog
- 02-companies: list + detail + add-membership dialog
- 03-reservations: berth list + detail reservations tab + reserve
  dialog
- 04-client-detail: list + detail walking every tab
- 05-eoi-generate: generate dialog opens with Documenso option
- 06-invoice-form: new-invoice dialog billing-entity toggle
- 07-berths: list + detail walking every tab
- 08-portal: client portal yachts / memberships / reservations
- 09-navigation: every primary nav target loads cleanly

Destructive specs (tests/e2e/destructive/):
- 01-yacht-archive: create-via-API → archive via UI → assert removed.
  Skips with a clear message when the global setup does not seed an
  owner client (avoids brittle failures while the full destructive
  fixture lands).

Playwright config: testDir hoisted to ./tests/e2e; new `exhaustive` and
`destructive` projects share the existing setup project. New scripts
test:e2e / test:e2e:smoke / test:e2e:exhaustive / test:e2e:destructive
in package.json drive each project independently.

CI integration deferred — no .github/workflows/* exists in this repo
yet, so the PR 14 task to wire a separate CI job is N/A. The new
projects will pick up automatically when a workflow lands.
