fix(cli): clean error on invalid share --expires-at and drop dead schemas

Address review findings on `bm cloud share`:

- `create` re-wrapped the `typer.Exit(1)` from `_parse_expires_at()` as a
  spurious "Unexpected error: 1" trailing line because the broad
  `except Exception` caught it (typer.Exit subclasses Exception). Parse and
  validate --expires-at before entering the try block so the error surfaces
  as a single clean message, and add the `except typer.Exit: raise` guard for
  parity with `update`/`revoke`.
- Strengthen test_create_share_invalid_expires_at to assert
  "Unexpected error" is absent, which was masking the bug.
- Drop unused PublicShareResponse/PublicShareListResponse schemas; responses
  are parsed as raw dicts, so the schemas were dead code.
