fix: improve host diagnostics, storage handling, and maintenance workflows

- add zero-downtime Proxmox TLS certificate refresh from the Security panel (#307)
- classify storage availability independently from missing capacity information (#309)
- update ZFS ARC sizing and safely reconcile conflicting module configurations
- preserve and restore migrated ZFS settings without overwriting later administrator changes
- stop memory optimization from forcing the kernel overcommit policy
- correlate multi-line OOM events and identify the affected LXC, cgroup limits, swap and killed process
- add selectable Bash prompt path styles and clearer shell activation guidance
- protect technical names during automatic translation and correct localized terminology
- update the Coral and VM/LXC Apps and Updates documentation, translations and screenshots
