[PATCH datacenter-manager v2 2/8] api types: subscription level: render full names

[Thomas Lamprecht <t.lamprecht@proxmox.com>]

The Display impl produced single-letter codes ("c", "b", "s", "p"),
forcing the dashboard to keep a private letter-to-name helper just
to render labels.

Switching Display to the full names is safe: FromStr is extended to
accept the names alongside the legacy single-letter codes, so any
previously serialised value still parses, and the only in-tree
caller of Display on this enum is the dashboard helper that this
commit drops. The level strings reported by the PVE/PBS API land in
unrelated String fields and are not touched.

Add Debug to the derives, required for assert_eq! over the level in
the upcoming key-pool tests.
