feat: allow saving to same SR series

[pedrokohler]

Context

Currently, users are unable to save to an existing SR series — each save operation creates a new series. This pull request introduces functionality that allows users to save a new instance to an existing SR series.

The behavior remains consistent with the current loading mechanism: the most recent instance will be the one displayed, as there is still no implemented method for selecting which instance to load. This change simply enables the ability to add additional instances to the same SR series, which mirrors the behavior seen when multiple instances already exist.

Changes & Results

Before:
Can only create new series

After:
Can still create new series

But can also save to a previsouly existing SR series

Testing

Bill had a PR for allowing SR to save to the same series, can you see if we need that too? it was long ago

@sedghi The other PR has been closed and won't be used. Bill asked me to open this new one.

This new PR is based on the old one, but uses the new ui-next dialog setup, and doesn't do anything weird with loading/display annotations.

There is still the ability to load previous versions, but that is an extension of this one. This menu will only appear when saving to a study that already has SRs, and it will default to the old behaviour.

@dan-rukas Can you please design this?

Criteria:
When saving a measurement the user has two options.

1. Whether to create a completely new series and name it and hit save
2. Whether to choose an already existing series (from a dropdown) and CAN"T rename it (only name is shown) and save

[dan-rukas]

Here's a quick mock-up to add some labels over the options. "Report Name" can still keep focus when the dialog comes up to allow for quick typing.
