Add MergerFS pool display to dashboard matching CLAUDE.md format

Updated the dashboard system widget to properly display MergerFS storage
pools in the exact format described in CLAUDE.md:

- Pool header showing "mergerfs (2+1):" format
- Total usage line: "├─ Total: ● 63% 2355.2GB/3686.4GB"
- Data Disks section with tree structure
- Individual drive entries: "│  ├─ ● sdb T: 24°C W: 5%"
- Parity drives section: "├─ Parity: ● sdc T: 24°C W: 5%"
- Mount point footer: "└─ Mount: /srv/media"

The dashboard now processes both data_drives and parity_drives arrays from
the agent data correctly and renders the complete MergerFS pool hierarchy
with proper status indicators, temperatures, and wear levels.

Storage display now matches the enhanced tree structure format specified
in documentation with correct Unicode tree characters and spacing.
