i18n(de): apply review round 1

- Meaning fixes: playback connects to the broadcaster when it starts, browser
  keys are restricted at the provider, clearing data layers switches them off
  (ausschalten, not löschen), cockpit inputs are Quellen, Electronic is
  Elektronische Musik, AIS types name vessels (SEGLER, LOTSENBOOT,
  SANITÄTSDIENST, SCHNELLSCHIFF), contiguous US excludes Alaska/Hawaii,
  wind and weather readings are model values, nearest frames are nearest in
  time, cloud imagery and the brightness filter say what they are.
- NHC/CPHC advisories are Lageberichte, not Warnungen; cyclone strings use
  Wirbelsturm throughout. Glossary updated.
- Grammar: " oder " keeps its space as a join separator, "{x} konnte nicht
  sauber beendet werden", Then: no longer doubles Dann, scene save reasons
  continue the sentence in lower case, neutral "Warten auf".
- Spacing between numbers and units in the remaining nine readouts.
- Reroute tooltip: German mode nouns keep their capital (Auto, Fahrrad).
- Built-in Nepal shot titles localize in every language: the legacy scene
  upgrade rebuilds its base shots without sourcePackId, so the pack's own
  shots in the scene now vouch for them.
- Layout: the layer status column no longer shrinks under a wide chip, and
  a mixed-case compound (ALPR-Kameras) may break at its hyphen; only capital
  codes (ADS-B, RTL-SDR) stay unbroken. WIRD AKTIVIERT overlapped the name.
  The Bhote step meta line may take a third line.
