FINERACT-2642: string param AS header interpolation

[terencemo]

Description

Besides the use of reporting params in report_sql in WHERE clause expressions, there are a couple of standard reports using the pattern ${param} AS header to configure the headers in the tabular output of the SELECT query. Currently no report has string parameters, but if such report is added, then it bypasses the prepared statement execution and needs to be handled safely. This PR implements type checking to only allow date/numeric params for this pattern.

@terencemo Would it be possible to cover with integration or E2E tests?

Not straightforward because no reports exists with string param in AS header interpolation pattern. Will have to create one for testing this scenario.
