alif/boards/OPENMV_AE3: Fix romfs partitions.

Summary

Update romfs partitions to reflect the latest layout.

Testing

This partitions split is what we've been actually using for a while, and it's working fine, I just forgot to update it.

Assessment

S Sonnet · high

Both items involve ROMFS on Alif/OpenMV hardware, but they address entirely different concerns. PR #18595 is a narrow partition layout correction for the OPENMV_AE3 board — fixing base address and size values to match production. Issue #18962 is a broad feature request asking for ROMFS write/erase from MicroPython, ioctl documentation, and bootable ROMFS support. The PR makes no changes to write/erase functionality, ioctl API, or documentation. It is a prerequisite-level fix (correct partition layout) for the platform in question, but leaves all of the issue's requests unaddressed.

Suggested action

Leave issue #18962 open. PR #18595 may be referenced as context for the Alif partition layout when implementing write/erase support, but it does not resolve any part of the feature request.
