cli: layered show interface, IEEE 802.3.2-2025 ethernet model

Import ieee802-ethernet-interface@2025-09-10.yang, from IEEE 802.3.2-2025,
and companion ieee802-ethernet-phy-type.yang, replacing the 2019 revision.
Operational interface speed moves to ietf-interfaces:speed, RFC 8343,
eth:speed is now obsolete.  Bump infix-interfaces.yang revision to track
the upgrade.

The CLI 'show interface' command renders interfaces as bottom-up layered
protocol rows.  Ethernet interfaces a new IEEE link-mode row (1000baseT,
10GbaseLR, ...) is added with 'duplex: full|half' in the DATA column.
Without link the ethernet row is the first row.  Tunnels and wifi follow
the same layering: gre/vxlan rows carry remote:/vni: tokens with optional
ethernet sub-row for the L2-bearing variants; wifi rows carry 'station' or
'access-point' ssid:, signal:, stations: tokens.

The detailed interface view gains a 'link mode' row carrying the same
label.

yanger populates phy-type and pmd-type from a static ETHTOOL link-mode
identity table keyed on (port, speed, duplex).  Both leaves are populated
for unambiguous media (copper, DAC, copper-T); for generic fiber where
the (port, speed, duplex) tuple can map to multiple PMDs (SR vs LR vs
ER, etc.) only the phy-type family identity is emitted — guessing the
PMD would be misleading.  Future SFP EEPROM reads (ethtool -m) could
refine pmd-type at runtime.  cli_pretty prefers pmd-type (specific) and
falls back to phy-type (family) for display.

yanger also emits ietf-interfaces:speed and fixes a long-standing
'auto-negotation' typo (yanger had never matched ethtool's correctly-
spelled JSON field, so operational auto-negotiation always read
'unknown').

No config migration needed: the only config-true leaf in the ethernet
container, auto-negotiation/enable, is unchanged across the model upgrade.

Closes #530
