* 🐛 Gate pastes on page load and harden base-shape lookup
Pasting while the workspace is still opening crashed the
session: the layer-order lookup called rseq on a missing
root children list.
Ignore paste events until the page objects are loaded (the
clipboard keeps its content, so retrying works), return empty
instead of throwing from the shared layer-order helpers, and
fall back to pasting at the pointer position when the selection
is detached from the shape tree. Selecting the page root keeps
working as before through the frame branches.
Closes#11666

* 🐛 Cover props paste and root-plus-other in paste guards
Address review follow-ups on the paste-before-init fix: gate
props pasting on page readiness like the shape entries, and
route root-plus-other selections without a base shape to the
pointer fallback instead of the unguarded else branch. Pin
single-root selection to the frame path with a regression test.

* ♻️ Hoist page lookup out of paste-shapes gate
Bind page and page-objects once in an outer let instead of
calling lookup-page twice (once for the readiness gate and
once inside the body). No behavior change.

* ♻️ Reuse bound ids in paste-shapes page lookup
Bind file-id and page-id once and pass them to the lookup-page
arity that takes both, instead of resolving the page twice and
rebinding file-id in the inner let. No behavior change.

Return nil from get-prev-sibling when the shape is no longer present in
the parent ordering so delete undo generation falls back to index-based
restore instead of crashing on invalid vector access.
