hotfix: prompt PBS encryption in attached-mode scheduled jobs + reorder backend menu

Two changes, both scoped to scripts/backup_restore/backup_scheduler.sh, worth
shipping to main ahead of the full v1.2.3 release PR:

1. Attached-mode PBS jobs never asked about encryption. `_create_job_attached`
   ran `hb_select_pbs_repository` and jumped straight to writing the .env with
   PBS_REPOSITORY / PBS_PASSWORD / PBS_BACKUP_ID — no `hb_ask_pbs_encryption`
   call, no PBS_KEYFILE / PBS_ENCRYPTION_PASSWORD emitted. The runner then
   invoked `proxmox-backup-client backup` without `--keyfile`, so every
   attached-mode backup landed on PBS unencrypted regardless of what the
   operator would have picked. Confirmed via `git show` on eight historical
   commits back to 61ff665c (beta 1.2.2.2) — the encryption call has NEVER
   been in the attached branch; the standalone `_create_job_new` branch had
   it since day one, they just diverged silently.

   Fix mirrors `_create_job_new` exactly (lines 413-443):
     hb_ask_pbs_encryption || return 1               # abort on cancel
     local pbs_kf_val=""
     [[ -n "${HB_PBS_KEYFILE_OPT:-}" ]] && pbs_kf_val="$HB_STATE_DIR/pbs-key.conf"
     lines+=(... "PBS_KEYFILE=${pbs_kf_val}" "PBS_ENCRYPTION_PASSWORD=${HB_PBS_ENC_PASS:-}")

   The Monitor Web path (flask_server.py::api_host_backups_job_create)
   already accepted pbs_encrypt_mode for both modes and passed it through
   correctly, so the fix is confined to the CLI wizard.

2. Backend selection menu reordered from `local | borg | pbs` to
   `pbs (recommended) | borg | local` so the recommended default sits at the
   top of the list. PBS gets the "(recommended)" suffix in its label.

Deployed and verified on the four test hosts (.50, .55, .89, .1.10) —
attached-mode wizard now shows the encryption dialog immediately after the
PBS job picker, and the .env carries PBS_KEYFILE + PBS_ENCRYPTION_PASSWORD
when the operator opts in.
