`resolve()` does not account for `kit.router.type: 'hash'`

[brunnerh]

Describe the bug

For hash based routes to work, the result of the function has to be <base>/#<route-path>, but currently the # is omitted.

Reproduction

StackBlitz

Broken path: <a href={resolve('/about')}>{resolve('/about')}</a><br>
Correct path: <a href="#/about">#/about</a>
