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).

The right border on the address prefix read as a stray vertical line
between the domain and the slug. Remove it and rely on the subtle
prefix background alone to separate the two parts.

The "Custom address" slug field sized its leftSection with a
character-count heuristic (label.length * 7 + 12), which over-estimated
the real width of the small dimmed domain prefix and left an ugly empty
gap between "docs.../l/" and the input text.
- Measure the real prefix width via a ref + useLayoutEffect (scrollWidth)
and feed it to leftSectionWidth so the slug sits flush against the
prefix, regardless of host length or font metrics.
- Restyle the prefix as an attached addon: subtle background, a right
divider border and input-matching left corner radii.
- Minor spacing tidy: description mb 4->6, action buttons mt xs->sm.
No behavior change: validation, availability probe, save/remove and the
reassign modal are untouched.

Add a retargetable, human-readable vanity link namespace /l/<alias> that
sits alongside the untouched /share/... routes.
- New share_aliases table (workspace-scoped, UNIQUE(workspace_id, alias),
page_id nullable ON DELETE SET NULL so the address outlives its target).
- ShareAliasRepo + ShareAliasService (create / no-op / 409 reassign guard /
availability / request-time readable-target resolution through the single
existing share boundary).
- Public ShareAliasRedirectController (GET /l/:alias) issues a 302 (never 301,
the target is mutable) to the canonical /share/:key/p/:slug page; unknown /
dangling / no-longer-readable aliases serve the SPA index with no leak.
'l/:alias' excluded from the global /api prefix.
- Authenticated ShareAliasController (set/remove/availability/for-page).
- Shared ASCII-only normalize/validate util (server + client copies).
- Client: Custom address block in the share modal (live normalize + debounced
availability + copy + reassign confirmation dialog).
- Unit tests: util, repo SQL-shape, service semantics, migration/entity sanity
(server jest) + client alias util (vitest).
