Expand session token statuses

Is your feature request related to a problem? Please describe.

I'm always frustrated when I see regular problems but cannot assign some well-known status to them. Session token is a good well-structed candidate. We did it once: https://github.com/nspcc-dev/neofs-api/issues/191. Now we also have validation on the SN side and now such errors can be seen by a user: https://github.com/nspcc-dev/neofs-node/pull/2731, https://github.com/nspcc-dev/neofs-node/pull/2727.

Describe the solution you'd like

Possible status codes:

1. Wrong token issuer/not signed by container owner
2. Invalid signature
3. Wrong session operation
4. Wrong container

Describe alternatives you've considered

Not sure all of them (or any of them) are required and having a separate code for them can make user's life easier but for the tests a well structured response for such an important NeoFS part may look pretty.

Start by reviewing neofs-api issue #191 and the linked neofs-node pull requests #2731 and #2727 to understand the existing session-token validation and status handling. Resolve which proposed statuses are required and define the API changes and tests needed for a structured response.
