jdaviz 3.9 updates

[kecnry]

This PR encompasses minor updates for when we want to update the min-pin on jdaviz to 3.9

Waiting for: jdaviz 3.9

• revert pin of jdaviz main (and use >=3.9 instead)

Will also get from upstream:

• lcviz support: fix data-menu item visibility cloned phase-viewer jdaviz#2640
• fallback on linked_by_wcs for configs without default_viewer jdaviz#2705
• Improve viewer creator styling jdaviz#2743
• support deleting all viewers without crashing app jdaviz#2745

TODO:

• revert 6a0086e once ephemeris component validation #78 is merged
• include migrate temporary disabling previews upstream kecnry/lcviz#3 if cubeviz spectral extraction live-previews jdaviz#2733 is accepted upstream
• include don't open data menu when populating phase viewer kecnry/lcviz#4 if Open data menu on new blank viewer jdaviz#2742 is accepted upstream (and included in 3.9)
• revert "delay overwriting existing registry item" from Viewer creator in app toolbar #94 if that is merged and allow overwriting existing registry entries jdaviz#2744 is accepted upstream
• if Viewer creator in app toolbar #94 is merged and support deleting all viewers without crashing app jdaviz#2745 is accepted upstream, remove lcviz styling to prevent closing default time-viewer.
• include updates for upstream migration from export plot to export plugin kecnry/lcviz#5 if Export plugin (deprecates/replaces "Export Plot") jdaviz#2722 is accepted upstream
• tests failing with jdaviz main #92
