fix(crypto-registry): normalize RFC/FIPS standard name formatting (#847)

This PR normalizes a few outlier `standard.name` strings in
`schema/cryptography-defs.json` to match the existing naming convention:
- `RFC 5297` -> `RFC5297`
- `FIPS 203/204/205` -> `FIPS203/FIPS204/FIPS205`

URLs are unchanged; this is a string-formatting consistency fix only.

Fixes #846
