Reverse the color palete for dark theme

Description

We need to reverse the color palette for dark theme.

In Jira color palette in light theme looks like:

and in dark theme:

Both checked buttons are signed as “dark green”. Atlassian reverse the color palette automatically when you switch a theme. So If you set a dark font on light background after switching to dark theme you’ll have a proper light font.

We need the same mechanism for External page.

This also causes a bug when editing the External share page



Also there was a mismatch in page theme editor theme when:
in global settings dark mode was disabled
users browser is set to darkmode

For testing:
Editor theme and inserted elements should behave similarly to editor in Jira,
for example:
dark text in light mode should turn light in dark mode (high contrast and visible)

Easiest way will be to compare editor behaviour/comments look between Jira and ESFJ.

Please check from both perspectives (both for light and dark mode):
check how comments posted from ESFJ look in Jira
check how comments posted from Jira look in ESFJ
