feat(FactSystem): add BulkRefreshJob / bulkRefresh() to replace scatter-shot refreshParameter calls

[DonLakeFlyer]

Summary

Adds a proper batch-parameter-refresh API to ParameterManager and uses it
to eliminate the post-compass-calibration popup spam described in #14347 /
#14346.

Problem

_refreshParams() in both the APM and PX4 sensor controllers called
refreshParameter() and refreshParametersPrefix() individually. The FC
is often slow to respond mid-cancel; every timed-out request fired a modal
"Parameter read failed" via QGC::showAppMessage, stacking dozens of
dialogs and freezing the UI.

Solution

BulkRefreshJob (new src/FactSystem/BulkRefreshJob.{h,cc}):
A QObject-child of ParameterManager that fires a batch of
PARAM_REQUEST_READ messages and retries (exponential back-off, up to
kMaxRetryRounds = 3 rounds) any that time out. notifyFailure = false
suppresses the user-visible modal while still logging and emitting
_paramRequestReadFailure for internal use. Self-deletes on completion.

ParameterManager::bulkRefresh() (new public API):
Accepts a list of exact names and/or wildcard prefixes (e.g. "COMPASS_*"),
resolves them against the known parameter set, deduplicates, and delegates to
BulkRefreshJob.

Sensor controllers updated to use a single bulkRefresh() call with
notifyFailure = false, replacing the old scattered individual-refresh loops.

QML (APMSensorsComponent.qml): signal handlers converted to arrow-function
syntax to fix qmllint warnings.

Test-speed note

_waitForParamValueAckMs and BulkRefreshJob::_retryBaseDelayMs are set to
50 ms under QGC::runningUnitTests() so the new retry tests complete in ~1 s
instead of ~19 s.

Test plan

• ctest -L Unit -R ParameterManager — all 19 tests pass (5 new tests added,
  including retry-succeeds and all-rounds-exhausted paths)
• Start a compass cal on ArduPilot, cancel mid-way → no flood of
  "Parameter read failed" modals; UI stays responsive
• Normal compass cal to completion on ArduPilot and PX4 → params repopulate,
  no popup spam

Addresses the compass-cal refresh spam described in #14347.
