This fixes an unstable automated test for the bank reconciliation widget so it behaves consistently. The change helps reduce false failures in quality checks, making releases and maintenance more predictable without changing user-facing functionality.

Field Service setup tours no longer depend on sample data, so they can run successfully in databases without demo content. The portal signature button alignment was also corrected for a cleaner customer-facing experience.

Prior to this commit, the tour was using a field that is generated from the demo data,
which is not right. Indeed, the `x_description` field is created from the demo data, so
it is not found during the tour when no demo data is installed and the tour fails.
