[ZEPPELIN-6323] Apply dark mode to the new UI
### What is this PR for?
This PR adds dark mode support and system theme integration for the
Zeppelin New UI. There were multiple demands such as
[ZEPPELIN-5062](https://issues.apache.org/jira/browse/ZEPPELIN-5602) and
[ZEPPELIN-4024](https://issues.apache.org/jira/browse/ZEPPELIN-4024).
#### Example: Follow system theme + other parts
https://github.com/user-attachments/assets/2159d54e-6403-4f80-91f0-3f66a93881e1
#### Example: Change with button + notebook
https://github.com/user-attachments/assets/59bdf1bc-86a3-42e1-a3d0-1d89d955ed7d
#### Automatic System Theme Detection & Sync
- Automatically detect OS-level dark/light mode settings
- Real-time detection and application of system theme changes
- Theme cycle pattern: `auto(system) → opposite theme → original theme →
auto`
#### Comprehensive Dark Mode UI Support
- Applied dark mode styles across all major components
- Added dark mode overrides for Ant Design components
- Full Monaco Editor dark theme support
- Consistent color scheme and visual hierarchy
#### Enhanced User Experience
- Eliminated FOUC (Flash of Unstyled Content) with logic handled in
`index.html`
- Easy theme switching via a toggle button
- Persisted user preferences in local storage
- Theme state maintained after page reloads
With dark mode support and system theme integration, Zeppelin delivers a
modern, user-friendly experience. Users can either rely on system theme
settings for automatic adaptation or manually select their preferred theme.
### What type of PR is it?
Improvement
### Todos
* [ ] I created a dark mode [background
image](https://github.com/dididy/zeppelin/blob/5d078a40c17e0561202e809da0761016516b86f2/zeppelin-web-angular/src/assets/images/bg-dark.png)
used for login and loading with ChatGPT, but I need to verify whether there
are any copyright issues.
* [ ] Due to the limited environment setup, I wasn’t able to check all the
cases where graphs are rendered. I think we can leave this as a follow-up issue
to work on later.
### What is the Jira issue?
* [[ZEPPELIN-6323](https://issues.apache.org/jira/browse/ZEPPELIN-6323)]
### How should this be tested?
### Screenshots (if appropriate)
### Questions:
* Does the license files need to update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
Closes #5078 from dididy/feat/darkmode.
