fix(ci): exclude signing spec from mock-based coverage config and bump thresholds

The signing spec requires real @stellar/stellar-sdk crypto (Keypair.random(),
authorizeEntry, xdr classes) which is incompatible with the moduleNameMapper
in jest-coverage.js that replaces the SDK with a mock. Exclude it from the
coverage config and run it in a separate CI step using the base jest config.

Also bump soroban.adapter.ts coverage thresholds to accommodate the new
client-signing seam methods.
