- Remove align-self: start from .polar-container so the grid row's
minmax(260px, 340px) height is actually respected
- Switch #polarPlot to aspect-ratio: 1/1 so the canvas is always square
- Fix both draw functions to size canvas from getBoundingClientRect on
the canvas itself (not parent) using min(width, height) for a square plot
- Remove min-height from .dashboard to prevent empty space below content
on narrow/mobile screens where stacked panels are shorter than 720px

- Move _passAbortController = null to after response.json() so the retry
scheduler cannot see a false idle state mid-parse, increment
_passRequestId, and discard the in-flight response — this was causing
non-ISS satellites to show no passes intermittently
- Add _computeSlantRange() helper using 3D ECEF geometry
- Update applyTelemetryPosition to compute slant range from SSE lat/lon/
altitude, giving distance updates at 1Hz instead of 5s HTTP poll rate

updateCountdown fell back to passes[0] even when it was in the past,
showing 00:00:00:00 with a stale satellite name indefinitely. Now
displays a clear 'NO UPCOMING PASSES' state with '--' for all fields
when no future pass exists in the current prediction window.
Consolidated to a single active-request guard with cleanup in finally.
The previous pattern had redundant null-checks across try and catch, and
an always-false check on a controller that was already null. Cancel-on-
new-request is now explicit before creating the new controller.
METEOR-M2 (NORAD 40069) is a weather satellite with LRPT downlink but
was missing from WEATHER_SAT_KEYS, so no capture button appeared in
the pass list. Adds it alongside M2-3 and M2-4.
Previously currentPos only had lat/lon, so the updateTelemetry fallback
(used before first live position arrives) always showed '---' for
altitude/elevation/azimuth/distance. currentPos now includes all fields
computed from the request observer location. updateTelemetry simplified
to delegate to applyTelemetryPosition.
Adds a 'source' param to handleLivePositions. The SSE path ('sse') only
applies lat/lon/altitude/groundTrack since the server-side tracker has
no per-client location. The HTTP poll path ('poll') owns all observer-
relative data and the visible-count badge.
