[fix](trx-frontend-http): record decode statistics for all decoder types

The "Decodes by type" statistics panel only showed AIS because
statsRecordDecode was only called from dispatchDecodeMessage, which
was bypassed by two code paths:

1. dispatchDecodeBatch: uniform-type batches dispatched to specialized
   batch handlers (onServerFt8Batch, etc.) returned early without
   recording stats.

2. restoreDecodeHistoryGroup: history messages restored on page load
   were never recorded in the statistics log.

Fix both paths by recording stats up-front in dispatchDecodeBatch
before dispatching to batch handlers, and in restoreDecodeHistoryGroup
before restoring to plugin views. Add a skipStats parameter to
dispatchDecodeMessage to prevent double-counting when the fallback
per-message loop runs inside dispatchDecodeBatch. Also accept an
optional timestamp in statsRecordDecode so history entries use their
original ts_ms rather than Date.now().
