Three issues in the satellite predictions view caused page-wide
rendering performance degradation:
1. Unbounded DOM nodes: All satellite passes (200+ satellites × multiple
passes = 500-1000 rows with 5 spans each) were rendered at once,
creating thousands of DOM nodes that slowed style recalculation and
layout across the entire page. Now caps at 50 visible rows with a
"Show more" button.
2. No DOM cleanup on view switch: Prediction rows persisted in the DOM
when navigating away from the predictions view or the SAT tab,
bloating the page DOM indefinitely. Now clears prediction DOM when
leaving the predictions view or switching decoder tabs.
3. Countdown timer never paused: The 1-second setInterval with
querySelectorAll kept running even when the predictions view was
hidden, wasting CPU on invisible DOM queries. Now only runs when
predictions view is active, caches element references instead of
querying the DOM each tick, and auto-pauses when the view is hidden.
Also caches prediction DOM element references at module init instead
of calling getElementById on every render invocation.

applyRigList() was called on every SSE state update (since `remotes`
is always present in the payload), and it unconditionally called
bmFetch() which fires 2x GET /bookmarks (list + overlay). At the
default poll rate this generated ~20 bookmark fetches/second — visible
as constant GET /bookmarks traffic on each spectrum render cycle.
Now track the previous rig list + active rig as a key and only
re-fetch bookmarks (and re-init scheduler/background-decode) when
the rig list actually changes.

Two issues introduced with wxsat/satellite support caused indirect
performance degradation on the spectrum rendering path:
1. spawn_tle_refresh_task() was called inside spawn_rig_audio_stack(),
which runs per-rig. With N rigs this spawned N redundant TLE refresh
tasks, each making 3 concurrent HTTP requests to CelesTrak and
competing for write locks on the global TLE store. Moved to a single
global call after the per-rig loop.
2. compute_upcoming_passes() (SGP4 propagation for 200+ satellites over
24h = ~300K propagation steps) ran on every GetSatPasses request with
no caching. Multiple client connections could trigger concurrent
CPU-heavy computations, causing cache pollution and tokio runtime
contention that indirectly slowed spectrum frame processing. Added a
60-second server-side cache shared across all client connections.

compute_upcoming_passes requires the TLE store to be populated by
CelesTrak fetches. If a client requests passes before the async NOAA
group fetch completes, NOAA-15/18/19 are missing from predictions.
Seed the store with hardcoded fallback TLEs synchronously in
spawn_tle_refresh_task before spawning the async fetch. CelesTrak
data overwrites these entries once fetched. Also adds pass sanity
tests for NOAA-15 and NOAA-18.

The noise floor subtraction was over-aggressive: the bandwidth ratio
scaling between the 67 kHz baseband probe and the IQ domain amplified
the noise estimate excessively, causing weak stations to be subtracted
to nothing. The pilot-referenced correction only worked for stereo
stations.
Strip the signal strength path back to what actually works universally:
mean IQ envelope power with asymmetric attack/decay smoothing. This
always produces a reading for any FM signal — mono, stereo, with or
without RDS.
The baseband noise probe, CNR estimation, and pilot metrics remain in
the WfmStereoDecoder for their existing uses (RDS quality weighting,
CCI/ACI estimation) but no longer feed into the S-meter.

Replace the simple IQ power averaging with a proper WFM signal
strength measurement algorithm based on established RF engineering
practice:
1. Asymmetric attack/decay smoothing (τ_attack=2ms, τ_decay=300ms)
per IARU Region 1 Technical Recommendation R.1 for professional
S-meter behaviour. Fast attack catches signal increases
immediately; slow decay provides stable, readable meter movement.
2. Baseband noise floor estimation via a 67 kHz probe in the
demodulated FM baseband. FM demodulation noise follows an f²
spectral shape, so energy above the useful baseband (audio +
RDS ≤ 57 kHz) is dominated by channel noise and independent of
program content. Subtracting this noise estimate in the linear
domain reveals the carrier-only power, preventing the meter from
reading the noise floor on empty/weak channels.
3. Pilot-referenced quality correction. The 19 kHz stereo pilot
has a known fixed amplitude at the transmitter (±7.5 kHz
deviation, 10% of ±75 kHz). Near the FM threshold (~10 dB CNR)
where noise dominates the IQ reading, the pilot tone power
provides an independent quality-weighted correction. The blend
factor scales from 0.3 at low CNR down to 0 at high CNR where
the raw IQ measurement is already accurate.
4. CNR estimation from the ratio of total baseband power to the
above-band noise probe, enabling adaptive pilot correction and
providing a signal quality metric for future use.

The previous carrier power IIR filtered |IQ|² (power), which only smoothed
temporal fluctuations but still integrated noise across the full 180 kHz WFM
channel bandwidth. This caused background noise to read ~-78 dBFS instead of
the expected ~-110 dBFS (~32 dB too high ≈ 10·log₁₀(180kHz/500Hz)).
Move the single-pole IIR lowpass to the IQ domain (filter I and Q separately
at ~500 Hz cutoff), then compute power from the filtered output. This rejects
out-of-band noise before the power measurement, so the meter reads true
carrier level rather than total wideband noise.
