fix: replace hardcoded npmx.dev & docs.npmx.dev with env-specific URLs

[serhalp]

Extract a composable that returns URLs for this app itself (and docs, which lives in this codebase), so that URLs are always internally consistent within an environment, e.g. in dev links go to dev.

📝 Walkthrough

Walkthrough

The pull request centralises URL configuration by introducing a new useAppUrls() composable that provides dynamic site and documentation URLs. Hard-coded URLs across multiple components and pages are replaced with calls to this new composable. The createWebSiteSchema() function signature is updated to accept a siteUrl parameter. Environment configuration is extended to expose siteUrl through the application configuration via getEnv(). Constants are renamed from NPMX_SITE to NPMX_SITE_PROD and a new NPMX_DOCS_SITE_PROD constant is added to shared utilities.

• refactor: add proper route segments for package code #1301: Both PRs modify canonical URL construction logic on the package-code page, with this PR injecting configurable siteUrl values.

[knowler]

wondering if we should or should not hardcode this? It is possible to pass flags with the dev command to change the port/host. Could we get that from somewhere else?

[danielroe]

unfortunately only 127.0.0.1 works for the atproto oauth callback

but yes, you can get the actual host and port in module space

the URL's are deterministic, so can we just construct them during the build?
