Remove ecdsa-keys compilation flag

[neuronull]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-38832

📔 Objective

We built with this flag as the default in #1181

, and now that the ssh agent in the clients repo supports the key type, there isn't a reason to have the compilation flag anymore, so this change is to remove it and cleanup.

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR removes the temporary ecdsa-keys compilation flag from bitwarden-ssh, making ECDSA key generation and import (P-256/P-384/P-521) unconditional now that the clients' SSH agent supports the key type. The change cleanly removes all #[cfg(feature = "ecdsa-keys")] gates, the reject_ecdsa_import guard and its single call site, and the obsolete import_ecdsa_blocked test, while promoting the previously gated ECDSA tests to run unconditionally. The feature flag is also dropped from the bitwarden-uniffi and bitwarden-wasm-internal dependency declarations.

Code Review Details

No issues found. The cleanup is complete and self-consistent:

• A repository-wide search confirms zero remaining ecdsa-keys references.
• The p256/p384/p521/ssh-key ECDSA dependencies were already unconditional, so removing the feature flag introduces no new build inputs or dependency changes.
• ECDSA import/export/generation paths remain covered by tests, which now execute by default.

Does not need my explicit approval, but from @bitwarden/wg-ssh-keys side looks great.
