Phase 1 & 2: Cleanup redundant code and integrate pattern decoder

## Phase 1: Code Cleanup (~1,859 lines removed)

**Deleted Redundant Matchers:**
- ❌ strategies_orm.py (356 lines) - Old ORM-based strategies
- ❌ simple_matcher.py (351 lines) - Replaced by strategies.py
- ❌ rtl433_matcher.py (352 lines) - Replaced by strategies.py

**Archived Old Scripts:**
- Moved 11 one-time analysis/import scripts to scripts/archive/
- Scripts: analyze_flipper_signatures, analyze_tembed_files, identify_tembed_devices,
  import_flipper_sqlite, import_tembed_signatures, match_tembed_with_db,
  match_with_flipper_db, rematch_captures, test_gps_extraction,
  test_tembed_matching, test_wardriving_import

**Consolidated API:**
- Renamed main.py → main_orm_legacy.py (archived old ORM-based API)
- main_simple.py is now the primary production API

## Phase 2: Pattern Decoder Integration ✅

**CRITICAL FIX: Pattern decoder now integrated into production API!**

**Changes:**
1. Updated main_simple.py to use unified SignatureMatcher
2. Added 6 strategies to matcher pipeline:
   - ExactMatcher (protocol + frequency)
   - FrequencyMatcher (frequency-based)
   - BitPatternMatcher (data patterns)
   - TimingMatcher (timing-based)
   - RTL433DecoderStrategy (RTL_433 decoder)
   - PatternBasedStrategy (NEW! Pattern decoder for short captures)

3. Created MockDB class for simplified mode (no real database)
4. Replaced old get_matcher() with get_matcher_engine()
5. Updated upload handler to use MatchResult format
6. All matches now include confidence scores and match methods

**Result:**
- Pattern decoder is NOW ACTIVE in production 🎉
- Unified matching pipeline with 6 strategies
- Cleaner codebase (-1,859 lines)
- Single source of truth for matching logic
