feat: fiber migration v2 -> v3

Fiber has released a new major version, **v3.0.0**, introducing several breaking changes. As part of the gateway migration from Fiber v2 to v3, the `filesystem` middleware has been deprecated and replaced with the `static` middleware for serving web assets. Currently, Fiber’s `static` middleware contains a bug in how it resolves the filesystem root path. Because of this, `fs.Sub` is used to set the embedded `web` directory as the effective root of the filesystem.
