chore: migrate repo to pnpm v11 (#48033)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Chore / dependency tooling update.

## What is the current behavior?

The repo is pinned to pnpm 10.24.0. Closes
https://linear.app/supabase/issue/FE-3673/migrate-the-repo-to-use-pnpm-v11.

## What is the new behavior?

The repo is pinned to pnpm 11.13.1, pnpm v11 workspace settings are
migrated to `allowBuilds`, and the Studio Dockerfile installs pnpm
11.13.1.

## Additional context

Validated with `CI=true mise exec node@22 -- pnpm install
--frozen-lockfile`, `mise exec node@22 -- pnpm run typecheck`, and `mise
exec node@22 -- pnpm run lint`; full Prettier check still fails on
existing generated docs/router files outside this migration.

## Summary by CodeRabbit

* **Chores**
* Updated tooling requirements (pnpm **11.13.1**, Node **>=22.13**) and
aligned container build tooling accordingly.
* Adjusted package manager behavior (scoped registry override, update
notifications disabled) and workspace build/engine validation settings.

* **Maintenance**
* Updated `clean` scripts across apps/packages to remove only
build/cache artifacts (no longer delete installed dependencies).
* Reduced Turbo `clean` task output to **errors-only** for cleaner logs.
