Проба доступности алиаса возвращала currentPageId — id страницы, на которую
алиас уже указывает — ЛЮБОМУ аутентифицированному участнику воркспейса без
проверки прав на просмотр этой страницы. Перебором имён алиасов можно было
смапить их на id страниц, к которым доступа нет.
Теперь checkAvailability отдаёт только {alias, valid, available}. Бита
taken/free достаточно для пробы; заголовок целевой страницы всплывает лишь
ПОСЛЕ реальной попытки setAlias (путь 409 ALIAS_REASSIGN_REQUIRED), который
проверяет права. Клиент currentPageId нигде не использовал — убран из типа,
стейта и теста. Серверный спек утверждает отсутствие currentPageId в ответе.

The share modal flagged a custom address already owned by another page with a
red "This address is already in use" error driven by the availability probe.
That reads as terminal even though Save actually triggers the server's
409 `ALIAS_REASSIGN_REQUIRED` and opens the "Move custom address?" confirm
modal that retargets the address to the current page — so the reassign path was
hidden behind what looked like a hard stop.
Replace the red error with an informational description hint ("This address is
in use. Saving will move it to this page.") and keep Save enabled, so the
existing confirm-reassign flow is discoverable. Renaming to a FREE name was
already correct (the probe returns available -> no error -> server renames the
single row in place); this only changes the taken-name presentation.
Verified end-to-end in a real browser against a live stand on this branch:
- A (free rename `test`->`test2`): 200, same alias row renamed in place, link
becomes `/l/test2`, no error, exactly one DB row for the page.
- B (`test2` owned by another page): hint shown (no dead-end error), Save ->
409 ALIAS_REASSIGN_REQUIRED -> "Move custom address?" modal -> confirm -> 200,
the single row retargets, one row each.
- C (same-name re-save): Save disabled (no-op); first-time set inserts.
Add a client component test covering both branches (taken name -> hint not
error + Save enabled; 409 -> reassign modal -> confirm sends confirmReassign).
