[frontend/backend] feat(profile): add XTM Hub newsfeeds preferences (#2136)

[Antoine-Quintin]

Proposed changes

• Add unsubscribed_news_feed_types field on User and MeUser GraphQL types
• Add unsubscribed_news_feed_types to ME_USER_MODIFIABLE_ATTRIBUTES to allow editing via meEdit mutation
• Add default resolver returning [] for users without existing preferences
• Add XTM Hub Newsfeeds preferences section in user profile page with global toggle and per-type toggles

Related issues

• Refers to 🎯 Add ability to update user preferences in OpenCTI profile page FiligranHQ/xtm-hub#2136
• Refers to Add XTM Hub newsfeeds preferences to user profile #15571

Checklist

• I consider the submitted work as finished
• I tested the code for its functionality
• I wrote test cases for the relevant uses case (coverage and e2e)
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality

Further comments

This PR is part of the XTM Hub newsfeeds feature (FiligranHQ/xtm-hub#528).
The available_news_feed_types field on Settings will be added in a separate PR
(depends on FiligranHQ/xtm-hub#2135). The frontend card is already in place and will
activate automatically once that PR is merged and rebased.
