Add to UI from Feedback

[mykalmax]

• [x] Control+Enter should execute query or current selection.
• [ ] This should work in the Custom SQL tab but would also be great if it resolved macros (especially the @start_date and @end_date ones) and it worked in the model code (ignoring the model definition, resolving to limit 1000)
• [x] Prefer dark mode anyways but coloring in light mode does not look right by default (see screenshot)
• [x] On rename file, enter should confirm
• [ ] Branch name should be shown in the UI somewhere
• [ ] In docs view, external models show the entirety of the YAML file, should be limited to the relevant section.
• [ ] Should be a link to switch to editor view and bring up the model source code from the docs view.
• [ ] the font in the hidden column mode should maybe be bumped 2 points (or make it configurable?)
• [x] preserve display options when clicking through a lineage node title
• [x] consideration for selective column expansion in column hidden mode -- ie show columns on one node while rest are hidden
• [ ] consideration that the most impactful upstream columns are usually the direct parent nodes? (column semi-hidden mode?)
• [ ] shift+click to copy column name to clipboard
• [ ] copy all columns to clipboard button too, comma separated with line breaks, ready to paste in projection and prune
