fix(api): typed OpenAPI query params and not-found messages that hide private projects

- Query DTO properties with a default value (limit, offset, days, perColumn,
  assignedToMe, search, archived, requiresReason, force) were documented as
  `object` in openapi.json, which broke generated clients. They now declare
  their type explicitly.
- Reading a private project, ticket, release or its comments without access
  answered "Project <internal id> not found", confirming the project exists.
  ReadAccess now reports what the caller asked for (e2e covered).
