[Feature Request]: Logic for numeric range manual input

In addition to...
> - Can't set either lower or upper bound to 'e'. (allowed by browser, NA in Shiny server)
> - Can't specify lower bound > upper bound

from https://github.com/insightsengineering/teal.slice/pull/226

Some additional logic for the manual numeric range are outlined as follows
- Entered range must be a valid numerical value (but allow scientific notation like 2E6 or 2e-2)
- Entered range can be smaller/larger compared to the actual range of the filtered data or the slider (also mentioned here https://github.com/insightsengineering/teal.slice/issues/230)
- Allow user to specify one-side bound, eg. if left blank, consider it to be `-Inf` or `Inf`, effectively max of the filtered data.
