[Feature Request] adding subpath support to logdy

[icyavocado]

Summary

Adding a --ui-path option to the CLI to allow subpath configuration for the web server (e.g., localhost:80/path).

Motivation:

This feature enables users to serve applications from specific paths, improving organization for multiple apps on the same server.

For example: example.com/logs for logdy only service

Implementation:

Include --ui-path option, modify routing logic, and update documentation accordingly.

Correct me if im wrong, there are 2 places that needed updating for this change to work:

1. Adding --ui-path option, and override the HttpPathPrefix, here is my draft in [#107] add --ui-path option #108
2. After the tweak, main.wasm will failed to load, since https://github.com/logdyhq/logdy-ui/blob/942a63a9be2c729e46463759f1b78ac4739bac73/src/breser.ts#L6 mapped to absolute path of the domain. I proposed a fix to use window.location.pathname to support subpath. In which I created a draft PR here [#107] support serving main.wasm via subpath logdy-ui#14
