Fix imported schematic symbol text moving separately in MatchPack

[KrishnaX12]

Problem

Imported symbol text was not associated with its schematic component. During MatchPack auto-layout, symbol artwork moved while reference/value labels stayed at the original position. This reproduces with the real SWRA117D antenna symbol imported from SQFMI Watchy.

Changes

• Associate schematic text inside a symbol with its owning schematic component.
• Add the Watchy antenna circuit-json symbol fixture, a minimal automatic-layout regression test, and a visual schematic snapshot.

Verification

• Repro branch test fails before the fix because the antenna labels lack schematic_component_id.
• Fix branch test passes and its snapshot shows readable labels beside the antenna.
• Related custom-symbol test passes; TypeScript and Biome checks pass.

Repro-only branch: main...KrishnaX12:repro/custom-symbol-matchpack

This is a draft pending maintainer review.
