[PATCH v4 0/5] client: repository: add individual component parameters

[Thomas Lamprecht <t.lamprecht@proxmox.com>]

Follow-up to [v3], reworked based on Wolfgang's and Christian's review
feedback - thx!

The compact repository URL format ([[auth-id@]server[:port]:]datastore)
can be cumbersome to work with when changing a single aspect of the
connection or when using API tokens. This series adds --server, --port,
--datastore, --auth-id, and --ns as separate CLI parameters alongside
the existing compound --repository URL.

Changes since [v3]:
- Deduplicated mutual-exclusion check into check_mutual_exclusion()
- Used AllOfSchema for mount.rs raw ApiMethod definitions
- Commands where --ns is irrelevant (login, logout, version, status, GC,
  benchmark, task) now use BackupRepositoryArgs only
- Moved optional_ns_param() to pbs-client tools as shared helper
- Fixed change_backup_owner not stripping atom fields before forwarding
- Small nits (anyhow::bail! -> bail!, private ENV_VAR_PBS_NAMESPACE)

Changes since [v2]:
- Deduplicated param resolution cascade into shared helper
- Split into BackupRepositoryArgs and BackupTargetArgs (repo + ns)

Changes since [v1]:
- Split single commit into five
- CLI atoms now merge with PBS_* env vars per-field (CLI wins)
- Fixed mutual-exclusion error swallowing and duplicate ns property
- PBS_NAMESPACE works uniformly across all three client binaries
