feat: initial napalm-yealink driver
Discovery-Fingerprinting für Yealink IP-Phones (T-series, W-series,
CP-series, VP-series) und Video-Endpoints.
- TYPE_LABEL = "Phone" (Override von AccessPointDriver)
- SNMP_OBJECT_ID_PREFIX = "1.3.6.1.4.1.37403" (Yealink Enterprise OID)
- HTTP_FINGERPRINT: "yealink" (mandatory, weight 10), Modell-Patterns
- get_facts(): liest phoneName + firmware aus dem noauth-API-Response
(/api/v1/system/info liefert Gerätedaten auch ohne Authentication)
- Login via MD5-gehashtem Passwort auf /api/v1/session/login (HTTPS)
