feat(jinja): improve url parameter formatting

[villebro]

SUMMARY

Add handling of special characters to URL param function in Jinja context to improve cross-database filter clause compatibility. This is done by adding the parameter escape_result to the url_param function which defaults to True. When enabled, it escapes the value of the requested url param using the relevant SQLAlchemy dialect for the selected database.
