Finding 1 (HandleReloadConfig data loss): move ClearCalibration inside
LoadSourcesFile so the table is wiped only after a successful fread.
Adds a clearCalibration bool parameter (default false); the reload path
passes true, the startup path passes false.
Finding 2 (JSON injection via unit/source/signal): add JsonEscape()
static helper (escapes \", \\, \n \r \t, and \u00XX for other control
chars). Applied at all three emission sites: BroadcastCalibration,
HandleSaveSources, and BroadcastSources (label). Teach JsonGetString to
unescape the same set on read, so values round-trip correctly.
Finding 3 (%.17g verbosity): add ShortFloat() static helper that tries
%.15g then %.16g then %.17g, stopping at the first precision whose
strtod() output compares equal to the original. Applied at both float
emission sites. 0.1 now prints as "0.1", not "0.10000000000000001".
Minor: fix two inaccurate comments in StreamHub.h — the CalibrationEntry
rationale (not a 133 MB / address-limit issue; the real reason is no
per-entry heap churn, STL-free, trivially copyable) and "chars" to "bytes"
for the unit cap.

- Add CalibrationEntry (heap-allocated array[256], char[] fields to stay within
the 133 MB struct's canonical address limit) plus calibrationMutex_ and
numCalibration_.
- Implement SetCalibrationEntry/ClearCalibration, BroadcastCalibration,
BroadcastConfigAck, HandleSetCalibration, HandleReloadConfig.
- Wire setCalibration and reloadConfig into OnWSCommand dispatch.
- Broadcast calibration to each newly connected client after triggerState.
- Fix JSON round-trip bug: replace JsonGetString/JsonGetBool helpers with a
shared whitespace-tolerant JsonFindValue (tolerates "key" : "value" as
written by HandleSaveSources); add JsonIsFinite (no <cmath>).
- Extend LoadSourcesFile(bool skipActive) to also parse calibration blocks;
SourceIsActive checks live sessions before starting a duplicate.
- Extend HandleSaveSources to persist calibration blocks; emit configSaved ack.
- Reload semantics: calibration replaced wholesale, sources added only.

Parse the optional +Recorder block in Initialise (Enabled/AutoStart/
Directory/MaxFileMB/KeepFiles/StagingMB/FlushIntervalSec/MinDiskFreeMB/
Signals, MB->bytes), apply it to each session before Start (static and
dynamic sources). Drive recorder disk I/O from the push loop via
RecorderFlushTick, and add recStart/recStop/recInfo WS commands plus a
recStatus broadcast/snapshot.
