docs: compass calibration time is configurable, not fixed at 30 s

[Raffi1202]

Problem

mag_calibration_time has shipped in 9.1 and 10.x for a long time (default 30, range 20 to 120 seconds), but two pages describe the magnetometer calibration as taking a fixed 30 seconds:

• docs/04-inav-configurator/calibration-tab.mdx:84 — "You have 30 seconds to hold the copter in the air"
• docs/04-inav-configurator/calibration-tab.mdx:92 — "After 30 seconds, the flight controller will sound a single beep"
• docs/05-core-features/compass.mdx:200 — "Within 30 seconds, hold the aircraft in the air"
• docs/05-core-features/compass.mdx:217 — "After 30 seconds, the flight controller will sound a single beep"

Someone who raises the value follows the text, stops moving the aircraft after 30 seconds and ends up with a half-finished calibration.

Change

Those four sentences now name the setting and its range instead of a fixed number. Wording only, no restructuring, and the other "30 seconds" mentions in the docs (gyro auto-calibration, autoland wind estimation, PID tuning) are untouched because they are unrelated.

Source

mag_calibration_time in docs/Settings.md on both release/9.1 and maintenance-10.x: default 30, min 20, max 120, "Adjust how long time the Calibration of mag will last."

Document configurable compass calibration duration

📝 Documentation 🕐 Less than 5 minutes

AI Description

• Documents mag_calibration_time defaults and supported range for compass calibration.
• Aligns completion-beep guidance with the configured calibration duration.

High-Level Assessment

The inline documentation approach is appropriate because users need the configurable timing details while following calibration instructions. Linking only to the settings reference was considered but would make the operational guidance less immediate.

Clarify configurable magnetometer calibration timing

• Documents 'mag_calibration_time', its default and supported range, and notes that the Configurator countdown follows the flight controller. Updates the completion-beep guidance to depend on the configured duration.

Use configured duration in compass calibration instructions

• Reframes the Configurator calibration window around 'mag_calibration_time', including its default and range. Clarifies that stick-command calibration completes when the configured time elapses.
