* WIP

* WIP

* feat: re-introduce generics

* WIP

* feat: introduce `AppState`

* WIP

* WIP

* fix: fix some `unwrap`s, clean code

* refactor: simplify agent_store

* feat: add `CommandHandlers` struct

* style: fix clippy warnings

* refactor: simplify Commands

* style: change name

* chore: add log messages

* fix: only update view when `CredentialOfferCreated`

* chore: add comments and logging

* refactor: separate queries

* fix: several fixes

* test: update postman collection

* fix: set `oid4vc` dependencies to specific `rev`

* chore: set `rust-version` and use `workspace.package` settings

* feat: add `GET` method for `credentials` endpoint

* test: add `GET` method for `credentials` endpoint in postman collection

This includes a test for the `POST` method for the `credentials`
endpoint that updates the `CREDENTIAL_LOCATION` environment variable

* chore: add `/v1/credentials/{credential_id}` to `openapi.yaml` file

* chore: bump `axum` dependency to `0.7`

* chore: update `axum` related code to version `0.7`

* feat: add `log_error_response` macro for cleaner logging of error responses

* chore: update POST request to a valid OBv3 `credentialSubject`

* feat: introduce secret manager (Stronghold)

* chore: use `TraceLayer` for proper tracing in `agent_api_rest`

* `on_request` makes sure that each request is traced
* `on_response` makes sure that each response is traced
* `on_body_chunk` makes sure that each response body is traced

`TraceLayer` only accepts `Request<axum::body::Body` which is not `Serialize`,
therefore, we still need to explicitly trace the request body in each route.

* feat: use `SecretManager` from external `producer`

* fix: remove obsolete `log_error_response` macro

The `log_error_response` macro is replaced by the `TraceLayer`.`

* refactor: use `if` + `is_err()` rather than `match` for `command_handler` useage

* feat: add `NOT_FOUND` response option

* refactor: revert changes to test subject

* feat: replace `did_key` with `did_manager` implementation

* test: use `tracing-test`

* chore: remove static secret `UNSAFE_ISSUER_KEY`

* refactor: reorganize imports

* chore: remove unused dependency `did-key`

* chore: update postman collection

* chore: use updated function from `secret_manager`

* style: fix clippy issues

* chore: remove `inspect()`

* ci: bump dependencies

* refactor: load `SecretManager` through `services.init()`

* refactor: use more generic naming for `SecretManager` commands and events
