Replace JSON-based backup system with SQLite export/import functionality:
**Export Features:**
- Generate SQLite database files with complete user data
- Export all tables: SSH hosts, credentials, file manager data, settings, alerts
- Include OIDC configuration and system settings (admin only)
- Password authentication required for data decryption
- Direct browser download instead of file path display
**Import Features:**
- Incremental import with duplicate detection and skipping
- Smart conflict resolution by key combinations:
- SSH hosts: ip + port + username
- Credentials: name + username
- File manager: path + name
- Re-encrypt imported data to current user's keys
- Admin-only settings import (including OIDC config)
- Detailed import statistics with category breakdown
**Removed:**
- Database backup functionality (redundant with export)
- JSON export format
- File path-based workflows
**Security:**
- Password verification for all operations
- SQLite file format validation
- Proper error handling and logging
- Admin permission checks for settings

Following Linus principle: "功能不完整就不应该暴露给用户"
BEFORE: F2 key only printed console.log - useless UI control
AFTER: F2 properly triggers onStartEdit for file rename
This was a classic "half-baked" feature that frustrated users.
F2 is a standard Windows/Linux file manager shortcut.
Note: Could not locate "Straight button" mentioned in issue.
Searched all UI controls, sorting, layout functions - not found.
May have been removed or misnamed.
The core F2 rename issue is now resolved.
Following "good taste" principles to separate create intent from actual files:
DATA STRUCTURE REDESIGN:
- Add CreateIntent interface to separate intent from reality
- Replace mixed virtual/real file handling with pure separation
- Remove isCreatingNewFile state that caused confusion
ELIMINATE SPECIAL CASES:
- Cancel operation now has zero side effects (was creating default files)
- Remove complex conditional logic in handleCancelEdit
- Separate handleConfirmCreate from handleRenameConfirm responsibilities
SIMPLIFY USER FLOW:
- Create intent → Show UI → Confirm → Create file
- Cancel intent → Clean state → No side effects
- No more "NewFolder" + "UserName" duplicate creation
UI COMPONENTS:
- Add CreateIntentGridItem and CreateIntentListItem
- Render create intent separately from real files
- Focus/select input automatically with ESC/Enter handling
Resolves: Users reporting duplicate files on creation
Core fix: Eliminates the "special case" of cancel-creates-file
Result: Predictable, elegant file creation flow
Following Linus's "good taste" principles to eliminate race conditions:
- Add request ID tracking to prevent concurrent request conflicts
- Simplify loadDirectory function by removing complex reconnection logic
- Add reconnection lock to prevent concurrent SSH reconnections
- Implement 500ms refresh debouncing to prevent spam clicking
- Separate concerns: connection management vs file operations
Eliminates "special cases" that caused random state corruption.
The data structure now properly tracks request lifecycle.
Resolves file folder refresh showing stale content issue.
This commit eliminates the confusing requirePassword field that was causing
authentication issues where users couldn't disable password requirements.
Changes:
- Remove requirePassword field from database schema and migrations
- Simplify SSH authentication logic by removing special case branches
- Update frontend to remove requirePassword UI controls
- Clean up translation files to remove unused strings
- Support standard SSH empty password authentication
The new design follows the principle of "good taste" - password field itself
now expresses the requirement: null/empty = no password auth, value = use password.
Fixes the issue where setting requirePassword=false didn't work as expected.
