Fix schematic section titles overlapping chip reference designators

[seveibar]

Schematic section titles can overlap the reference designator above the top-left chip because section bounds only include component bodies. Include component-owned reference/value text in those bounds and keep the bottom of each title above the section contents, accounting for sectionTitleFontSize.

Adds a visual regression covering a chip and a chip-backed schematic box on separate sheets, with default and enlarged titles. Refreshes affected section snapshots and the existing RC-car title-position expectations. Completes the plated-hole test's upstream change to check hole-pair errors consistently, without requiring dependency-specific courtyard errors.

Validation:

• The regression fails against the original section renderer and passes with the fix.
• bunx tsc --noEmit passes.
• All seven tests that failed in the initial CI run pass locally after refreshing the remaining snapshots and correcting the plated-hole assertion.
• Visually inspected the new two-sheet regression render.
