fix(matrix-static-files): restore /.well-known serving with static-web-server v2.41.0

Users reported that /.well-known/matrix/* stopped being served after the image bump to static-web-server v2.41.0.

Regression introduced by commit 32aeaca28b in PR #4951: https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/4951

Root cause: upstream changed hidden-file handling defaults, so paths under /.well-known were treated as hidden and no longer served by default.

Fix by explicitly configuring SERVER_IGNORE_HIDDEN_FILES=false in the matrix-static-files role and rendering it as a JSON boolean in the env template, making behavior stable across upstream default changes.
