feat(spec): element:button declares the action it executes — InlineActionSchema (objectui#2997)

element:button's renderer reads `properties.action` and dispatches it
through the ActionRunner — it is the only thing making a standalone-page
button interactive — and ElementButtonPropsSchema did not declare it.

It is authored anyway: cloud's service-tenant pages carry five sites across
the billing and pricing funnel, each `{type:'navigation', to: …}`, each cast
`as any`.

An undeclared prop is STRIPPED, not ignored — safeParse returned success
with no `action` in `data`. Harmless only because page block `properties`
are still z.record(z.string(), z.unknown()); the moment that is tightened
to validate against ComponentPropsMap, every one of those buttons loses its
action at save with a green parse.

InlineActionSchema is derived, not a new dialect. ActionSchema is
z.object(…).refine(…).refine(…), so `.pick()` is unavailable on the export;
the object half is now a factory both build from, preserving lazySchema's
deferral. The inline schema picks the twelve fields element:button actually
forwards, sharing their describe() text, the ActionType vocabulary and the
target-required refinement.

`name`/`label` are optional — a registry entry needs an identity and a menu
label, an inline action has neither (the button supplies its own label).
Registry-only concerns are excluded, as are icon/variant (the button has its
own) and body (a page button running a sandboxed script is a separate
decision).

`navigation` and `to` become normalizing aliases folding to `url`/`target`,
the VIEW_FILTER_OPERATOR_ALIASES pattern: cloud's pages keep validating
while output is always canonical, and the aliases can be tombstoned once
producers migrate. `url` is also the better target — its runner path has
${param} interpolation, apiBase promotion and popup-safe openIn; the
navigation path has none of those.

NOT done: promoting `navigation` into ActionType bare (declined in #4070) —
it names the type while leaving the prop undeclared and `to` homeless, and
adds a permanent synonym to a vocabulary whose members cannot be removed.

Nothing narrowed; all generated surfaces gain entries only. spec suite
7038/271 green, tsc clean, all twelve check:* gates pass.

+feat(spec): `element:button` declares the action it executes — `InlineActionSchema` (objectui#2997)
+
+`element:button`'s renderer reads `properties.action` and dispatches it through
+the `ActionRunner`; that prop is the only thing making a standalone-page button
+interactive. `ElementButtonPropsSchema` declared `label`, `variant`, `size`,
+`icon`, `iconPosition`, `disabled`, `aria` — and no `action`.
+
+It is being authored anyway. cloud's `service-tenant` pages carry five
+declaration sites across the billing and pricing funnel (`pricing`, `welcome`,
+`billing-cancel` ×2, `billing-success`), each `{ type: 'navigation', to: … }`,
+each cast `as any` to get past the type system.
+
+**An undeclared prop is stripped, not ignored.**
+`ElementButtonPropsSchema.safeParse({ label, action })` returned `success: true`
+with no `action` in `data` — a non-strict `z.object` drops unknown keys. That is
+harmless only because page block `properties` are still
+`z.record(z.string(), z.unknown())`, so this schema never runs on a real page
+save. The moment anyone tightens `properties` to validate against
+`ComponentPropsMap` — an obvious hardening — every one of those buttons loses its
+action at save, with a green parse. Declaring the prop is what defuses it.
+
+**`InlineActionSchema` is derived, not a new dialect.** `ActionSchema` is
+`z.object(…).refine(…).refine(…)`, so `.pick()` is unavailable on the exported
+schema — the object half is now a factory both schemas build from, which keeps
+`lazySchema`'s deferral (the fields are constructed on first use of whichever
+schema is touched, not at module load). The inline schema `.pick()`s the twelve
+fields `element:button` actually forwards to the runner, so their `describe()`
+text, the `ActionType` vocabulary and the `target`-required refinement are shared
+rather than restated.
+
+`name` and `label` are optional, which is the substantive difference:
+`ActionSchema` requires both because a registry entry needs an identity and a
+menu label, and an inline action has neither — the button already has its own
+`label`, and requiring `action.label` too would mean writing it twice. Everything
+that only means something for a registered action — `objectName`, `locations`,
+`order`, `ai`, `requiredPermissions`, `visible`/`disabled`, `resultDialog` — is
+excluded, as are `icon`/`variant` (the button has its own) and `body` (a page
+button running an inline sandboxed script is a separate decision). A declared
+field no renderer reads is the failure this schema exists to stop, so widen it
+when a renderer widens, not before.
+
+**`navigation` and `to` become normalizing aliases, not new members.**
+`normalizeInlineAction` folds `type: 'navigation'` → `'url'` and `to` → `target`
+on parse, the `VIEW_FILTER_OPERATOR_ALIASES` pattern. So cloud's existing pages
+keep validating unchanged while parse output is always canonical, and the aliases
+get a `retiredKey` tombstone once the producers are migrated. `url` is also the
+*better* target: the runner's `url` path has `${param.X}` / `${ctx.X}`
+interpolation, `apiBase` promotion for `/api/…` paths and popup-blocker-safe
+`openIn`, none of which its `navigation` path has.
+
+Deliberately **not** done: promoting `navigation` into `ActionType` as a bare
+member, which was considered and declined in #4070. It would name the type while
+leaving the prop undeclared and `to` homeless — half a fix, and a permanent
+synonym in a vocabulary whose members cannot be removed later.
+
+Nothing is narrowed. `ui/InlineAction` and `ui/ElementButtonProps:action` are
+additions to every generated surface; no accepted value stops being accepted, so
+no stored page metadata changes meaning.
+
+Verified: 16 new tests — the derivation is asserted from both directions
+(the inline field set is exactly the documented twelve; every one of them
+round-trips through `ActionSchema`; every registry-only concern is absent; every
+`ActionType` member is inline-authorable), and the fold is pinned against the
+literal shape cloud writes. Full `@objectstack/spec` suite **7038 tests across
+271 files**, `tsc --noEmit`, and all twelve `check:*` gates, clean.
