refactor(sub-blocks): delete fetchOptions — a sub-block's options are a selector or derived, never both

Completes the migration. `fetchOptions`/`fetchOptionById` are off `SubBlockConfig`,
off both controls, and out of `useFetchedOptions`, leaving exactly two ways a
sub-block gets its options:

  selectorKey  — a registered selector. The ONLY way to load a remote list.
                 Parameterized by an explicit SelectorContext, so it works on the
                 canvas, in the fork sync modal, and anywhere else.
  options      — a static array, or a pure function of the block's own values.
                 No I/O.

Reading the remaining callsites showed most of the "derived" ones were nothing of
the kind — they were workspace-scoped remote fetches wearing a local-looking
signature. Those became seven `workspace.*` selectors (credential providers,
credential groups + their per-group providers, secret names, raw secret names,
sandboxes, trigger types) plus `providers.openrouterEmbeddingModels`. Only the
agent block's three capability dropdowns were genuinely derived; `options` now
takes the block's values so they can say so directly. The parameter is optional,
so every existing zero-argument options function is untouched.

`imap.mailboxes` is the one selector whose account is typed rather than stored.
Its password is deliberately absent from the query key: a query key identifies a
resource, a credential authorizes access to it. `oauthCredential` is safe there
because it is only an id — a typed password is a secret, and keys are cached and
surfaced by devtools. Host, port, TLS and username already identify the mailbox
list uniquely; the password rides the body exactly as before.

`selectorExcludeSelf` replaces the one thing a shared `sim.workflows` selector
could not express. It is a declared flag rather than a blanket rule because the
answer differs per field: the Sim trigger never receives events about its own
workflow, while the Logs block legitimately reads the logs of the workflow it
runs in.

Deletes `lib/workflows/subblocks/options.ts` and `triggers/editor-state.ts`
entirely — every caller was a `fetchOptions` resolver. The live-registry test for
the trigger vocabulary moves to the selector that now owns it, keeping its
lazy-import cycle guarantee under test.
