fix: resolve all 281 credo issues across source and test files
- F-level (228): replace length/1 with Enum.count_until/2 or pattern
  matching; convert Enum.flat_map+if to Enum.filter+Enum.map; fix
  identity case in narr_client
- W-level (46): normalize dual atom/string key access in weather_layers,
  beacon_measurements, surface, skewt_live, contact_live/show; add
  :data_provider and weather-map assigns to ignored_assigns in credo
  config (consumed by child components credo can't trace); remove
  weak is_list assertion; remove explicit assert_receive timeout
- R-level (6): replace 'This module provides...' moduledocs with
  meaningful descriptions
- Also fix 4 compile-connected xref issues by deferring
  BandConfig.band_options() from module attribute to runtime
