Skip locationless schematic text

[ShiboSoftwareDev]

What changed

AltiumTS now renders schematic text records only when the source record contains a location.

Why

Altium stores simulation-model metadata as parameter records without LOCATION.X or LOCATION.Y. The SVG renderer treated missing coordinates as (0, 0), so unrelated strings such as SPICE netlist templates were all drawn on top of each other along the lower-left edge of the sheet.

Locationless records do not have drawable placement information. Skipping them preserves every normally positioned label while removing the invented pile of simulation text.

Testing

• Added a focused SVG snapshot test with a locationless simulation parameter beside a positioned annotation.
• Updated the existing Hyperpolyglot schematic snapshot; only the locationless metadata disappears.
• bun test tests/svg/schematic-locationless-text.test.ts tests/svg/sample-schematic-sheet.test.ts --max-concurrency=1
• SVG suite: 99 passed; its only initial failure was the intentionally changed Hyperpolyglot snapshot, which was regenerated and then passed.
• bun run format:check
• bun run typecheck
• bun run build
