Remove @requiresauth from these public release operations.

Both operations are documented and routed as unauthenticated SDK endpoints, but the Smithy trait still declares authentication mandatory. Generated clients and OpenAPI consumers may consequently require credentials for public boot requests.

185-195: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Run database migrations before the signingkeys backfill.

signingkeys triggers the backfill but does not set should_run_db_migrations. With MIGRATIONS_TO_RUN_ON_BOOT=signingkeys, startup skips the table migration, the backfill queries a missing signing_keys table, logs the failure, and continues without provisioning keys.

Proposed fix
 let should_run_db_migrations = migrations_to_run_on_boot.iter().any(|m| m == "db");
+let should_run_signing_key_backfill =

Inline comments:
In `@airborne_dashboard/components/settings/integrity/signing-keys-card.tsx`:
- Around line 48-53: Update the useSWR state in the signing-keys card to capture
error alongside data, isLoading, and mutate, then render a dedicated error state
with a retry action using mutate when the request fails. Ensure the “No signing
keys” empty state is shown only after a successful response with no keys, not
when data is undefined because of an error.

In `@airborne_docs/docs/dashboard/integrity.mdx`:
- Around line 39-43: Update the key ID validation list in the integrity
documentation to state that IDs must be no longer than 50 characters, alongside
the existing character, dash, and boundary constraints.

In `@airborne_docs/openapi/airborne.openapi.json`:
- Line 2120: Update the signing-key list description associated with the
relevant OpenAPI endpoint to remove the guarantee that the list is never empty.
State that automatic default-key provisioning applies to newly created or
backfilled applications, while preserving the existing details about ordering,
public-key-only responses, headers, and authentication.
- Line 2865: Add operation-level security overrides with an empty array to both
ServeReleaseV2 at airborne_docs/openapi/airborne.openapi.json:2865-2865 and
ServeRelease at airborne_docs/openapi/airborne.openapi.json:2989-2989, so these
public operations do not inherit the document-level bearer authentication
requirement.
- Around line 2891-2897: Update the signing-key parameter schemas for
ServeReleaseV2 at airborne_docs/openapi/airborne.openapi.json:2891-2897 and
ServeRelease at airborne_docs/openapi/airborne.openapi.json:3015-3021 to accept
either an empty string or a valid non-empty key ID. Replace the conflicting
minLength/pattern constraints with a schema expression that preserves the
existing key-ID validation while allowing the documented empty-value default
behavior.

In `@airborne_server/src/config.rs`:
- Around line 173-175: Update the master_encryption_key handling near its
initialization and the encrypt_private_key provisioning flow so signing
private-key encryption remains mandatory regardless of USE_ENCRYPTED_SECRETS.
Require a dedicated encryption key for signing keys, or reject provisioning when
none is configured; never allow encrypt_private_key to persist plaintext PEM
data.

In `@airborne_server/src/release.rs`:
- Around line 1465-1469: Update the signing-key ID extraction in the request
handling flow to distinguish a missing header from a present header containing
invalid UTF-8. Reject the request when x-signing-key-id cannot be converted to
text, rather than passing None to signing::utils::requested_key_id and selecting
the default key; preserve existing behavior for valid and absent headers.

In `@airborne_server/src/release/utils.rs`:
- Around line 496-509: Update invalidate_release_cache to invalidate both the
existing /release/{organisation}/{application}* path and the v2 endpoint path
/release/v2/{organisation}/{application}. Submit both paths together through
invalidate_cf as a single invalidation batch, preserving the current best-effort
error logging.

In `@airborne_server/src/signing/utils.rs`:
- Around line 323-336: Update signature_cache_key and the surrounding signing
flow to resolve the authoritative active signing key before reading the cache,
then include the resolved key identity and a digest of body in the cache key
alongside the existing release context. Ensure cache hits cannot bypass key
resolution or return signatures for disabled/replaced keys, and update all
affected call sites in the signing and invalidation paths. Add regression
coverage for body mutation and concurrent mutation/invalidation so stale
in-flight signatures are not served.
- Around line 153-168: Require a configured master encryption key in
encrypt_private_key and fail with the existing ABError mechanism when it is
absent, rather than returning the plaintext key. Update the corresponding
decrypt_private_key behavior as needed to preserve encrypted-key handling, and
ensure provisioning propagates the failure instead of persisting or exposing the
raw private key.

In `@airborne_server/src/utils/db/models.rs`:
- Line 250: Remove the Debug derive from both private-key-bearing model structs
near the Queryable/Selectable declarations, including the model containing
private_key_encrypted, so debug formatting cannot expose encrypted private keys;
preserve the other derives unchanged.

In `@airborne_server/src/utils/redis.rs`:
- Around line 200-253: Make index_add and index_drop atomic by replacing their
multi-command Redis flows with Lua scripts executed through the existing Redis
connection. The index_add script must perform SADD and EXPIRE together, while
the index_drop script must read the set members, delete those members, and
delete the index within one atomic operation. Preserve the current error metrics
and ABError handling around the script executions.

In `@smithy/models/signing.smithy`:
- Around line 32-34: Update the signing model documentation around the
default-key description and the list guarantees at the referenced symbols to
state that an application may temporarily have no keys and therefore no default
key when provisioning fails; remove any claim that the key list is never empty
or that exactly one default always exists, while preserving the behavior for
applications with a configured default.
