Adds two console commands (registered only on the classic BL602 SDK path, not PLATFORM_BL_NEW): - BL602PartitionInfo: reads the flash JEDEC id and parses the partition table, printing a human-readable summary of entries, sizes and the active table (read-only diagnostics). - BL602RepartitionPSM: rewrites the PSM partition entry (erases and updates the partition table via the SDK PtTable API) so the config partition can be relocated/resized. Verifies the target address/size before committing. Motivation: CozyLife-based BL602 devices (1 MB flash) ship with a PSM (EasyFlash config) partition of only 8 KB. That is too small for OpenBeken to reliably persist its configuration, so config saves fail on those devices. BL602RepartitionPSM lets you relocate/enlarge the PSM partition from the console to give OpenBeken enough room to store its config, without reflashing the whole device. Useful for diagnosing and fixing flash layout differences between BL602 board variants from the device console.

Summary
Adds two console commands, registered only on the classic BL602 SDK path (not
PLATFORM_BL_NEW):BL602PartitionInfo— reads the flash JEDEC id and parses the partition table, printing a human-readable summary of entries, sizes and the active table (read-only diagnostics).BL602RepartitionPSM— rewrites the PSM partition entry (erases and updates the partition table via the SDKPtTableAPI) so the config partition can be relocated/resized. Verifies the target address/size before committing.Motivation
CozyLife-based BL602 devices (1 MB flash) ship with a PSM (EasyFlash config) partition of only 8 KB. That is too small for OpenBeken to reliably persist its configuration, so config saves fail on those devices.
BL602RepartitionPSMlets you relocate/enlarge the PSM partition from the console to give OpenBeken enough room to store its config, without reflashing the whole device.BL602PartitionInfois also handy for diagnosing flash layout differences between BL602 board variants directly from the device console.Files

BL602RepartitionPSMerases and rewrites the partition table. It verifies the target address/size before committing, but it is inherently a destructive flash operation — happy to split it into a separate PR (info-only vs. repartition) if preferred.
