fix: elliptic to noble

[dargmuesli]

This pull request migrates the elliptic curve cryptography implementation from the deprecated elliptic library to the more modern and actively maintained @noble/curves library. The changes focus on updating the EC JWK-to-PEM conversion logic to use the new library.

Resolves:

• Consider switching to a better-maintained library for Elliptic Curve Cryptography #193
• GHSA-848j-6mx2-7j84

Changes:

• Replaced the elliptic dependency with @noble/curves in package.json
• Switched all curve operations to use @noble/curves's p256, p384, and p521 implementations
• Refactored the key conversion logic to use @noble/curves APIs for point creation, public key derivation and validation
• Added an explicit check that the derived public key from the private key matches the provided public key
• Updated the PEM encoding logic to work with the new key representations and byte formats used by @noble/curves

Any updates on this? There is another vulnerablity in a dep of elliptic (bn.js)
