Sync main to develop

[Teeldinho]

Synchronize develop with main after the release merge so the branches stay aligned.

What this release contains

• Mobile gameplay overlay/layout fix: the run and jump controls are now anchored independently from the contextual action panel, so prompts like Enter Library and Enter Guard Room no longer push the gameplay controls sideways.
• Mobile action panel stabilization: the contextual prompt slot is out of flow and the action panel keeps a stable footprint on compact phones and tablet landscape.
• Home action placement update: the Home button now sits to the right of the HP badge on tablet/mobile, and at the far right of the desktop header beside Settings.
• Mobile home hero polish: authenticated status copy and the mobile orientation notice are centered on small screens.
• Regression coverage: added/updated tests for the mobile overlay anchors, header placement, and home hero alignment.

Validation already completed on the release branch

• npm run lint:fix
• npm run typecheck
• npm run test
• npm run ci:local

This PR is a sync-only follow-up to the release merge; it does not introduce additional changes beyond bringing develop up to the same merge commit now present on main.
