fix: pipeline editor badge requires asset-parse, not just main-function parse

A pipeline script's asset lineage is load-bearing — a deploy that can't parse
assets silently records no edges. The editor "parsable" dot only reflected
inferArgs (the main function), so a body the asset parser rejects (e.g. a
trailing `/////` in DuckDB) still showed green and deployed with empty lineage.

ScriptEditor gains `requireValidAssets` (set by the pipeline pane); when on, the
EditorBar badge is green only if BOTH the main function and inferAssets parse,
with the tooltip distinguishing "Main function not parsable" / "Assets not
parsable" / "Parsable".
