fix: update metar endpoints for raw_metar app

[tabrindle]

TLDR: Updated the raw_metar app to utilize the new Data API from Aviation Weather. The old API was deprecated.

Changes Made:

• Updated API endpoint from /cgi-bin/data/metar.php to /api/data/metar
• removed www subdomain to avoid redirects (now uses aviationweather.gov directly)
• Maintained all existing functionality and configuration options
• improved text wrapping to avoid word splitting

Testing:

• Tested with Pixlet render using multiple airport codes (KMCO, KJFK, KSFO, KORD)
• Verified API returns METAR data correctly with new endpoint
• Confirmed no linting errors or breaking changes

Background:

• The AviationWeather Data API was redeveloped in 2025, deprecating the old /cgi-bin endpoints in favor of streamlined /api/data endpoints.
• This update ensures the raw_metar app continues to function with the new API infrastructure.
• I am the author of this app and have tested the changes locally.
