feat(config): consolidate configuration with smart dependency resolution (ADR-021)

Simplifies configuration by consolidating overlapping settings and adding
automatic dependency resolution. This makes semantic search configuration
significantly easier for users while maintaining 100% backward compatibility.

## Key Changes

### Variable Renaming (Backward Compatible)
- `VECTOR_SYNC_ENABLED` → `ENABLE_SEMANTIC_SEARCH` (old name still works)
- `ENABLE_OFFLINE_ACCESS` → `ENABLE_BACKGROUND_OPERATIONS` (old name still works)
- Deprecation warnings logged when old names used
- Old names will be removed in v1.0.0

### Smart Dependency Resolution
- `ENABLE_SEMANTIC_SEARCH` automatically enables background operations in multi-user modes
- No need to set both `ENABLE_OFFLINE_ACCESS` and `VECTOR_SYNC_ENABLED` anymore
- Single-user mode doesn't auto-enable background ops (not needed)

### Explicit Mode Selection (Optional)
- New `MCP_DEPLOYMENT_MODE` environment variable
- Valid values: single_user_basic, multi_user_basic, oauth_single_audience,
  oauth_token_exchange, smithery
- Removes ambiguity about which deployment mode is active
- Falls back to auto-detection if not set (existing behavior)

### Configuration Templates
- Reorganized `env.sample` by deployment mode with clear sections
- Added mode-specific quick-start templates:
  - `env.sample.single-user` - Simplest configuration
  - `env.sample.oauth-multi-user` - Recommended multi-user
  - `env.sample.oauth-advanced` - Token exchange mode

## Implementation Details

### Files Modified
- `nextcloud_mcp_server/config.py` - Smart dependency resolution helpers
- `nextcloud_mcp_server/config_validators.py` - Simplified validation, explicit mode
- `tests/unit/test_config_validators.py` - 19 new tests (60 total, all passing)
- `env.sample` - Reorganized by deployment mode
- `docs/configuration.md` - Complete rewrite with consolidated approach
- `docs/troubleshooting.md` - New consolidation troubleshooting section
- `README.md` - Updated variable references

### New Files
- `docs/ADR-021-configuration-consolidation.md` - Architecture decision record
- `docs/configuration-migration-v2.md` - Comprehensive migration guide
- `env.sample.single-user` - Single-user quick-start template
- `env.sample.oauth-multi-user` - OAuth multi-user quick-start template
- `env.sample.oauth-advanced` - Token exchange quick-start template

## User Impact

### Before (Confusing)
```bash
ENABLE_OFFLINE_ACCESS=true      # Why both?
VECTOR_SYNC_ENABLED=true        # What's the relationship?
```

### After (Simplified)
```bash
MCP_DEPLOYMENT_MODE=oauth_single_audience  # Explicit (optional)
ENABLE_SEMANTIC_SEARCH=true                # Auto-enables background ops!
```

### Benefits
- 📉 2 fewer variables to understand for semantic search
- 📋 Clear intent ("I want semantic search")
- 🎯 Explicit mode declaration available
- 🔄 100% backward compatible
-  All 265 unit tests passing

## Testing
- All 60 config validation tests passing
- 10 new tests for configuration consolidation
- 9 new tests for explicit mode selection
- Full unit test suite: 265 tests passing
- Backward compatibility verified

## Migration
Users can migrate at their own pace. Old variable names continue working
with deprecation warnings. See docs/configuration-migration-v2.md for
detailed migration instructions.
