Alan Agius c75f60ef8a fix(platform-server): secure location and document initialization against SSRF and path hijack
Normalizes the URL and path parsing logic inside platform-server by consolidating security checks and normalizations into a single, unified parseUrl helper function.

This includes:
- Collapsing multiple consecutive leading slashes and backslashes (e.g., // or /\) to a single forward slash to avoid protocol-relative parsing of path-like & relative inputs.
- Rejecting malformed absolute URLs that are otherwise accepted by lenient DOM parsers like Domino but rejected by standard WHATWG parsers, preventing SSRF / allowedHosts validation bypasses.
- Ensuring parseDocument gets the fully parsed and normalized URL instead of raw, unvalidated configuration values, preventing virtual document hostname adoption/origin hijack.
- Moving parseUrl unit tests into a dedicated url_spec.ts test file to keep platform_location_spec.ts clean and decoupled.
