feat: Emission intensity plot has a selectable scenario source and scenario

[MonikaFu]

• depends on add all scenarios to output of prep_emissions_trajectory() workflow.pacta.dashboard#40 (add prep_emissions_trajectory() workflow.pacta.dashboard#26 was superseded)

Currently we fix a scenario in the plot but because we now have global selectors it makes more sense to make it possible for the user to select a scenario they want to view in this plot.

FYI @jdhoffa this is a new feature so I am not going to tackle it while re-sizing this plot and removing the filters but it should be added before we release the dashboard.

This will likely require two main components:

1. time_line.js will, at a minimum, need to be modified so that it filters the data by the selected scenario, e.g. here
   

   pacta-dashboard-svelte/src/js/time_line.js

   Lines 47 to 51 in 2395257

   	let subdata = data
   	.filter((d) => d.asset_class == asset_class)
   	.filter((d) => d.sector == sector)
   	.filter((d) => d.allocation_translation == allocation_method)
   	.filter((d) => d.equity_market == equity_market);

2. workflow.pacta.dashboard will need a bespoke, modified version of pacta.portfolio.report:::prep_emissions_trajectory() that does not filter the data to one specific scenario defined by the select_scenario_other and/or select_scenario arguments.

@cjyetman are you able to handle the worfklow.pacta.dashboard portion of that?
do you have enough context to do so?

I think so. I'll give it a go.
