Detailed Description

RAII guard that temporarily swaps SCHEMATIC::CurrentSheet to a given path for the duration of a scope, restoring it on exit.

SCH_SYMBOL / SCH_FIELD property and bounding-box getters look up the active instance through SCHEMATIC::CurrentSheet(); the differ and the geometry extractor both need that to point at the item's own sheet path while they read it. SCHEMATIC::CurrentSheet() returns a non-const reference even off a const SCHEMATIC*, so no const_cast on the schematic itself is needed.

A null aPath leaves CurrentSheet untouched (only the original value is saved and restored), matching the differ's nullable-path call sites.
