docs(home-lab): NAS/storage strategy page (needs hardware specifics from user)

[JacobPEvans]

Goal

Create a Mintlify docs page covering the home lab NAS/storage strategy.

Why this needs user input

Storage strategy depends on hardware specifics:

1. ZFS pool layout — pool names, RAID-Z configuration, disk sizes, cache/log devices. These are physical and not derivable from any repo.
2. NAS share map — which shares serve which workloads (Proxmox VM disks, container volumes, media, backups).
3. Capacity tiers — hot SSD vs cold HDD vs offsite cold storage. What lives where.

Proposed page

• Path: infrastructure/storage-strategy.mdx
• Sidebar group: Infrastructure
• Tier: 2
• Key sources: ansible-proxmox (ZFS roles, storage config), terraform-proxmox (storage module)

Done definition

• Pool layout documented (sanitized — no serial numbers or real device paths).
• Share map captured.
• Tiering decisions explained.
• Linked from infrastructure/overview.mdx.
