Move Uptime after the bar block in platform top tables

Uptime placement was the most visibly drifty ordering on platform top
tables: Proxmox and TrueNAS sat it at position 3 (before any bars),
Docker / vSphere at position 8 (after bars), Kubernetes Nodes at the
very end (after Capacity). Same monitoring concept rendered in three
different positions depending on the table.

Lock in the convention: Uptime is monitoring state, not identity. It
canonically sits between the bar block (CPU / Memory / Disk / Storage,
plus the Temp diagnostic) and the inventory counts.

Apply that rule:
  - Proxmox host model: Uptime moves from position 3 to position 7
    (Node, Version, CPU, Memory, Disk, Temp, Uptime, VMs, CTs, Cluster).
  - TrueNAS systems table: Uptime moves from position 3 to position 7
    (System, Version, CPU, Memory, Storage, Temp, Uptime, Pools,
    Datasets, Disks, Apps).
  - Kubernetes nodes table: Uptime swaps with Capacity so Uptime sits
    between the bars and the Capacity inventory string (Node, Cluster,
    Roles, Kubelet, Runtime, CPU, Memory, Uptime, Capacity).

The columnAlignment.ts docstring now documents the recommended column
ordering (identity → context → state → bars → diagnostic → time →
inventory → external) alongside the kind-to-align mapping, so the
ordering convention sits in the same source-of-truth file every agent
already reads when editing a platform table.

Other ordering questions (where integer counts sit relative to bars;
where the cluster-reference column sits) are left as each table's
current choice. They are defensible either way and have a real visible
UX cost to change. Revisit if drift surfaces.
