Extend BridgeDb metabolite ID coverage and add compound-name lookup

[Copilot]

BridgeDb support in the web converter was limited to a subset of metabolite identifiers and lacked name-based lookup. This update expands BridgeDb conversions for MS-relevant identifiers and enables identifier retrieval from compound names via BridgeDb search.

• Conversion surface expansion

  • Added BridgeDb source codes for:
    • casno (Ca)
    • inchikey (Ik)
  • Added explicit conversion entry points:
    • from_casno()
    • from_inchikey()
  • Switched conversion registration to generate all pairwise conversions across supported BridgeDb identifiers, so newly added ID types are automatically exposed in the converter matrix.

• BridgeDb name search support

  • Added BridgeDbSearch endpoint (/Human/search/).
  • Added from_name() to support compound_name -> <BridgeDb identifiers> conversions via BridgeDb search.

• Response parsing robustness

  • Extended BridgeDb response parsing to accept both datasource labels and BridgeDb system codes (e.g., PubChem-compound and Cpc), preventing dropped mappings when response format varies.

self.codes.update({
    "casno": "Ca",
    "inchikey": "Ik",
})

self.endpoints["BridgeDbSearch"] = "https://webservice.bridgedb.org/Human/search/"

async def from_name(self, name):
    response = await self.query_the_service("BridgeDbSearch", name)
    return self.parse_attributes(response) if response else None

• Fixes Extend BridgeDb identifier conversions #176

@copilot mark the test checking for availability of the CIR service with xfail and skip other tests using the service in case it is not available

Implemented in commit cb25284. test_service_available in tests/test_CIR.py is now marked xfail for CIR outage exceptions, and test_format now skips when the CIR service is unavailable.
