Add dash length and gap props for schematic line and path

[rushabhcodes]

What changed

Adds dashLength and dashGap support to <schematicline /> and <schematicpath />, matching the existing dash_length and dash_gap fields in circuit-json.

Why

circuit-json already models dash length and gap for schematic lines and paths, but @tscircuit/props did not expose corresponding JSX props. This lets consumers configure schematic dash patterns through props instead of being limited to the default dashed behavior.
