feat(beacons): plot-path link seeds TX chain to match beacon EIRP
The "Plot path to beacon" action now includes `tx_power_dbm` and
`src_gain_dbi` in the /path query string so the path calculator's TX
side emits the same EIRP as the beacon out of the box. The beacon
schema stores `power_mw` as EIRP already (per Beacons.RangeEstimate),
so we take 10·log10(power_mw), split against a default 30 dBi dish,
and clamp the TX power to a 0 dBm floor so very-low-EIRP beacons
produce a sane gain/power split instead of -10 dBm outputs.

Examples:
  10 W EIRP (40 dBm)  → 30 dBi dish + 10 dBm TX
  100 W EIRP (50 dBm) → 30 dBi dish + 20 dBm TX
  100 mW EIRP (20 dBm) → 20 dBi + 0 dBm (clamped)
