Fix the WizMote Ethernet pairing note and drop em dashes

[bharvey88]

The WizMote page said pairing on the Ethernet firmware waits 30 seconds on each radio channel and to allow a few minutes. That misreads the firmware.

In CAST-1_ETH.yaml the scan interval is 2 seconds, and the 30000 ms check is an idle threshold, not a per-channel dwell:

interval:
  - interval: 2s
    ...
    return want && (millis() - id(wizmote_last_packet_ms) > 30000);

wizmote_last_packet_ms is only assigned after the early return that rejects any MAC that isn't already paired, so during pairing it never updates. The device hops channels every couple of seconds and sweeps all 13 in well under a minute.

Telling someone to wait a few minutes hides a real pairing failure behind expected behavior.

Also replaces the five em dash placeholders in the Sensor Definitions configuration table with n/a.

• Documentation
  • Updated CAST-1 Ethernet firmware pairing guidance to reflect faster channel cycling and typical pairing within one minute.
  • Clarified unavailable configuration settings by replacing dash placeholders with “n/a” in sensor setup documentation.

Walkthrough

The CAST-1 documentation now describes updated Ethernet pairing timing and uses n/a for configuration settings without values.

Changes

CAST-1 Documentation

Layer / File(s)	Summary
Ethernet pairing guidance docs/products/cast1/examples/wizmote-blueprint.md	The pairing note describes channel scanning every few seconds and pairing within about one minute while a button is pressed.
Configuration placeholders docs/products/cast1/setup/sensor-definitions.md	Entries without values use n/a for firmware, WizMote, reboot, and factory-reset settings.

Poem

A bunny reads the pairing guide,
“Press the button,” it hops beside.
Channels scan, the link is near,
n/a makes blank fields clear.
CAST-1 docs now shine bright!
