build configure-workflow urls via URLSearchParams; keep ROUTES as pure paths

[frano-m]

Context

Raised during review of #1484.

CONFIGURE_WORKFLOW / CONFIGURE_ORGANISM_WORKFLOW in packages/shared/routes/constants.ts now embed a ?trsId={trsId} query string, which is filled by replaceParameters — a path tool doing a raw String.replace with no URL-encoding.

This works today only because every caller pre-sanitizes trsId to [a-zA-Z0-9-] (via formatTrsId). A future value containing &, =, #, or a space would break the URL silently. The ROUTES.CONFIGURE_ORGANISM_WORKFLOW.split("?")[0] in the e2e spec is a tell that a path constant is being used as something it isn't.

Proposal

Keep ROUTES entries as pure path templates and build the query string at the call site using URLSearchParams, e.g. a small helper:

buildConfigureWorkflowUrl(entityId, trsId) // -> "/data/assemblies/<id>/analyze/workflows?trsId=<encoded>"

Acceptance criteria

• ROUTES contains no embedded query strings.
• Configure-workflow URLs are built via URLSearchParams (proper encoding).
• No .split("?") workarounds in tests.
