Render schematic document parameter values

[ShiboSoftwareDev]

Why

Schematic title blocks store text such as =Title and =Revision, while the actual values live in hidden document parameters. The SVG renderer was drawing the references literally, so title blocks did not show the values Altium shows.

What changed

• Resolve document-level parameter references case-insensitively before rendering schematic text.
• Follow chained document parameters, such as DocumentNumber referring to SheetNumber.
• Leave project/runtime references unchanged when their value is not present in the .SchDoc.
• Keep component-owned parameter text out of document-level resolution.
• Add a focused one-test SVG snapshot and update the real Elk Pi schematic snapshot.

No geometry, font, color, or placement transformations were added.

Verification

• bun run format:check
• bun run lint
• bun run typecheck
• focused SVG tests
• all locally available tests (the optional TI bundle could not be downloaded because TI returned HTTP 403)
• bun run build
