chore: sync 2.4.1 onto master

[piotr-iohk]

This PR records the shipped 2.4.1 hotfix on master so the next release does not reuse those changelog entries.

Do not merge release-2.4.1 (#678). That branch was cut from v2.4.0 and already contains later 2.5.0 work on master.

Description

• Bumps CURRENT_PROJECT_VERSION 195 → 196 and MARKETING_VERSION 2.4.0 → 2.4.1
• Inserts the shipped ## [2.4.1] changelog section
• Removes consumed changelog.d/next/ fragments: fix: stop auto-accepting stale monitors #664, fix: fail closed without vss auth #665, fix: harden shop payment bridge #668, fix: consume vss-client 0.5.23 #673

Greptile Summary

Records the shipped 2.4.1 hotfix on master so its changelog fragments are not reused by the next release.

• Updates the app, notification extension, and widget extension to build 196 and marketing version 2.4.1 across Debug and Release configurations.
• Adds the 2.4.1 security release notes and advances the Unreleased comparison link.
• Removes the four consumed security changelog fragments.

Confidence Score: 5/5

The PR appears safe to merge because the release metadata is internally consistent and every removed fragment is preserved in the 2.4.1 changelog.

All relevant application and extension configurations receive the same version values, and the changelog consolidation retains each consumed security entry without changing executable behavior.
