Improve I/O performance with ramdisks

[adamoutler]

To significantly improve performance in the devcontainer, this commit mounts the /api and /log directories as ramdisks.

The following changes were required to support this:

• Permissions: Added the SYS_ADMIN capability and apparmor=unconfined security option to allow the container to perform the mount operation.
• Repository Structure: Removed now-obsolete .gitignore files and added .git-placeholder files to ensure the target directories exist. The original /.gitignore maintains the desired effect.

As a security enhancement, the container no longer runs with the --privileged flag, adhering to the principle of least privilege.

I had a cache issue which the page refused to load on a full rebuild. I marked it as draft immediately. I cleared the cache and it started working.
