✨ Audrey ✨ e66a1f37b5 Extract urlOriginsMatch utility and refactor senderIsInternal (#19076 )

Adds urlOriginsMatch to @bitwarden/platform, which compares two URLs by
scheme, host, and port. Uses `protocol + "//" + host` rather than
`URL.origin` because non-special schemes (e.g. chrome-extension://)
return the opaque string "null" from .origin, making equality comparison
unreliable. URLs without a host (file:, data:) are explicitly rejected
to prevent hostless schemes from comparing equal.

Refactors senderIsInternal to delegate to urlOriginsMatch and to derive
the extension URL via BrowserApi.getRuntimeURL("") rather than inline
chrome/browser API detection. Adds full test coverage for
senderIsInternal.

The previous string-based comparison used startsWith after stripping
trailing slashes, which was safe in senderIsInternal where inputs are
tightly constrained. As a general utility accepting arbitrary URLs,
startsWith can produce false positives (e.g. "https://example.com"
matching "https://example.com.evil.com"). Structural host comparison
is the correct contract for unrestricted input.
