docs: point README badges + NIGHTLY_STATUS at v4.1-dev (new default)

[shumkov]

Issue being fixed or feature implemented

v4.1-dev is now the repository default branch. The README codecov badges and NIGHTLY_STATUS links still pointed at v4.0-dev, so they no longer reflect the mainline — codecov's default-branch coverage and the scheduled/nightly workflow both run against the default branch (now v4.1-dev).

What was done?

Repointed the live branch pointers v4.0-dev → v4.1-dev (2 files, 9 references):

• README.md — codecov coverage badges (overall + per-crate) and the "Nightly Tests" link
• NIGHTLY_STATUS.md — the nightly-run description and the Actions branch-filter links

Left untouched: the book/ source permalinks and other blob/v4.0-dev/... links — v4.0-dev still exists as the 4.0.x maintenance branch, so those resolve fine (they intentionally reference maintenance-line source). This PR only fixes the pointers that should track the default/mainline branch.

How Has This Been Tested?

• grep confirms zero remaining v4.0-dev in the two edited files.
• Docs-only change; no code paths affected.
