* Reset contract state when dkg needs rerun * Reset nym-api for rerun * Gateway updates signer APIs at runtime * Fix clippy * Add epoch id * Use IndexedMap for shares * Query with epoch id * Add Clone to client traits * Pass nyxd client instead of api data * Get the specific epoch vk * Make wasm work * Remove wasm test runs As there are no wasm tests and the target_arch macros are not compatible with the cargo test environment, we can safely remove (for now) the wasm test target runs. * Put epoch_id in storage pk * Gateway uses old keys but current verifiers * Add group contract to env * Move group msg in common * Only run DKG if part of group * Clippy test * Rename wasm_storage to wasm_mockups * Update changelog
