Add Show Entries of Subgroups feature

Add Show Subgroup Entries feature with intelligent Group column management

This PR implements "Show subgroup entries in entry list view" setting that allows users to view entries from nested subgroups with intelligent Group column display management.

This feature brings KeePassXC closer to feature parity with the original KeePass application, which has long supported the ability to view entries from subgroups in a flattened list. This functionality is particularly valuable for users who organize their passwords in hierarchical structures but want the convenience of seeing all related entries at once without navigating through multiple subgroups or resorting to use search functionality for viewing subgroup entries.

Technical Implementation

Modified Components

• EntryModel: Enhanced setGroup() to conditionally use entriesRecursive() instead of entries() when feature is enabled
• EntryView: Added intelligent Group column visibility management with enhanced header menu and column toggle functionality
• Configuration: Integrated setting persistence and automatic UI refresh on configuration changes
• State Management: Proper tracking of user column preferences across different viewing modes

Key Changes

• Modified EntryModel::setGroup() for conditional recursive entry fetching
• Enhanced column visibility logic in entry view headers
• Added configuration UI integration in General settings
• Maintained full backward compatibility with existing search functionality

AI Disclosure

This pull request was created with the assistance of GitHub Copilot AI using the Claude Sonnet 4 model.

Features Added

Configuration Setting

• Added GUI_ShowSubgroupEntries configuration option (default: false)
• Integrated into the General settings tab with a user-friendly checkbox: "Show subgroup entries in entry list view"

Core Functionality

When enabled, the entry list view displays all entries from the current group and all its subgroups recursively, providing a flattened view of the hierarchical structure.

For example, with this group structure:

Root
├── Work (2 entries)
│   ├── Projects (5 entries)
│   └── Archive (3 entries)
└── Personal (1 entry)
    └── Banking (2 entries)

Selecting the "Work" group with the feature enabled shows all 10 entries (2 + 5 + 3) in a single list.

Intelligent Group Column Management

• Auto-show: Group column automatically appears when subgroup entries is enabled, since entries from different groups are displayed together
• User preference respect: If user manually hides the Group column while in subgroup mode, the preference is remembered
• Smart reset: When the feature is toggled off/on, user preferences reset to allow the Group column to auto-appear again
• Search mode compatibility: Maintains existing behavior in search mode where Group column is always available

Screenshots

Testing strategy

• Manually tested that new setting enables viewing subgroups and Group column
• Verified that disabling setting restores normal functionality and removes Group column
• Verified that Group column can be hidden while new setting is enabled and column stays hidden unless setting is disabled and re-enabled again

Type of change

• ✅ New feature (change that adds functionality)

I think we should move this to the View menu since you may want to toggle this type of view on/off. We also need to think about cleaning up the EntryView/EntryModel ... this has gone through a lot of iterations over the years and can be much cleaner.

Agree, that would be more logical place for the option.
That's where KeePass has this option (View→Show entries of Subgroups).

[droidmonkey]

There are a few fringe case issues with this change.

1. When you select the option from the view menu, the currently displayed entries do not change. Only the group column is shown. When selecting the group again from the group list the entries update properly.
2. Unsorted entries allow you to move them up/down in the list, this is an awkward thing when showing subgroup entries.

Recommend combining the view menu entry in the same partition as the "Show Group Panel" and "Show Preview Panel"
