v4.0.1

# Tinyauth v4.0.1

Hey everyone, this is a simple patch release to fix some issues that occurred with v4.

> [!WARNING]
> This release contains a security fix regarding label discovery, please update as soon as possible.

## Improvements

- Move docker connection check to start-up so as label discovery can fail in case of a socket proxy crash
- Use GIN recovery module to translate panics to 500 errors
- Sort OAuth providers based on name length
- Allow root cookie domain redirects
- Use more verbose logging for the `trace` log level
## Fixes

- Ensure data directory exists on docker images
- Remove trailing spaces before checking OAuth username and name
- Do not use container name for label discovery
## Technical

- Use docker meta flavors for images
- Bump dependencies

Please let me know of any issues so as I can fix them as soon as possible.
