fix: remove duplicate base uv.lock from workflows (forward-port #13326 to main) (#13427)

fix: remove duplicate uv.lock from workspace member

Forward-port of #13326 to main. The monorepo should keep only one
uv.lock at the workspace root; src/backend/base/uv.lock was a stale
duplicate. The scheduled nightly build runs from main's workflow
definition, so create-nightly-tag still ran
`git add ... src/backend/base/uv.lock` against a tree where the file
no longer exists, failing with exit 128.

- Delete src/backend/base/uv.lock
- nightly_build.yml: drop base-dir `uv lock` regeneration and the
  base lockfile from `git add`
- Remove COPY/bind-mount of the base lockfile from all Dockerfiles
- Makefile: lock_base/lock now lock only the root workspace
- changes-filter.yaml: drop the base lockfile path
- .secrets.baseline: shift nightly_build.yml line number 305 -> 304

Fixes the failing nightly:
