Fix: Auto-play only regenerated audio (front or back, not both) for bg-bg cardsv0.8.0

- Removed duplicate fyne.KeyA handler that was triggering both front and back audio
- Added SetAudioFileNoAutoPlay() method for controlled playback
- Front audio (a key) now auto-plays only front audio
- Back audio (A key) now auto-plays only back audio
- Refactored startPlayback to use startPlaybackForFile for better control
- Fixed icon reset when playback finishes for each audio type separately

-## Audio Regeneration Issue - Bulgarian-Bulgarian Cards
-
-### Issue Description
-
-When using keyboard shortcuts to regenerate audio on Bulgarian-Bulgarian (bg-bg) cards:
-- **Expected**: `a` regenerates front audio, `A` regenerates back audio
-- **Problem**: User reports that `A` is regenerating the "other side" instead of the back audio
-
-### What Should Happen
-
-For a bg-bg card with:
-- Front word: "котка" (cat)
-- Back definition: "домашно животно" (domestic animal)
-
-**Playback:**
-- `p` (lowercase p) should play audio_front.mp3 (pronunciation of "котка")
-- `P` (uppercase P) should play audio_back.mp3 (pronunciation of "домашно животно")
-
-**Regeneration:**
-- `a` (lowercase a) should regenerate audio_front.mp3 for "котка"
-- `A` (uppercase A) should regenerate audio_back.mp3 for "домашно животно"
-
-### Current Implementation
-
-#### File Structure (Correct as of Jan 21, 2025)
-```
-~/.local/state/totalrecall/cards/[CARD_ID]/
-├── word.txt              # "котка"
-├── translation.txt       # "котка = домашно животно"
-├── cardtype.txt          # "bg-bg"
-├── audio_front.mp3       # Audio for "котка"
-├── audio_back.mp3        # Audio for "домашно животно"
-└── [other files...]
-```
-
-#### Code Logic
-
-**Playback** (working correctly):
-- `SetOnTypedRune()` in app.go (lines 2445-2452)
-  - `p/п` → calls `a.audioPlayer.Play()` → plays `audio_front.mp3`
-  - `P/П` → calls `a.audioPlayer.PlayBack()` → plays `audio_back.mp3`
-
-**Regeneration** (potentially buggy):
-- `onRegenerateAudio()` (app.go lines 1034-1125)
-  - For bg-bg: calls `generateAudioFront(cardCtx, wordForGeneration, cardDir)`
-  - `wordForGeneration = a.currentWord` (the front word)
-  - Generates audio for the front word ✓ CORRECT
-
-- `onRegenerateBackAudio()` (app.go lines 1128-1191)
-  - Extracts: `translation = a.currentTranslation`
-  - Calls: `generateAudioBack(cardCtx, translation, cardDir)`
-  - Should generate audio for the back definition
-  - **VERIFY**: Is `a.currentTranslation` actually the back definition?
-
-### Debugging Steps
-
-#### 1. Check Card Files
-```bash
-# Navigate to an existing bg-bg card directory
-cd ~/.local/state/totalrecall/cards/[CARD_ID]/
-
-# Verify card type
-cat cardtype.txt          # Should be "bg-bg"
-
-# Verify translation file format
-cat translation.txt       # Should be "front_word = back_definition"
-
-# Verify audio files exist
-ls -lh audio_*.mp3        # Should see audio_front.mp3 and audio_back.mp3
-```
-
-#### 2. Check UI State When Loading Card
-When you open a bg-bg card in the GUI:
-1. Check the "Card Type" dropdown - should show "Bulgarian → Bulgarian"
-2. Check the Bulgarian input field - should show the front word
-3. Check the translation field - should show the back definition (not English!)
-4. The placeholder text should say "Bulgarian definition..." not "English translation..."
-
-#### 3. Test Playback (Working Baseline)
-Open a bg-bg card and test:
-- Press `p` (lowercase) - which audio plays? (Front word or definition?)
-- Press `P` (uppercase) - which audio plays? (Front word or definition?)
-
-#### 4. Test Regeneration
-After confirming playback works correctly:
-- Press `a` (lowercase) - which TEXT is sent for audio generation? Check console output for:
-  ```
-  Generating front audio for '[TEXT]'
-  ```
-- Press `A` (uppercase) - which TEXT is sent for audio generation? Check console output for:
-  ```
-  Generating back audio for '[TEXT]'
-  ```
-
-### Data Flow for `A` (Regenerate Back Audio)
-
-```
-User presses 'A'
-  ↓
-SetOnTypedRune() case 'A', 'А'
-  ↓
-onRegenerateBackAudio()
-  ↓
-Get translation:
-  - translation = a.currentTranslation
-  - IF empty: translation = a.translationEntry.Text
-  ↓
-generateAudioBack(cardCtx, translation, cardDir)
-  ↓
-Generate audio for [translation] → audio_back.mp3
-```
-
-### Potential Issues to Investigate
-
-1. **`a.currentTranslation` not set correctly**
-   - Check if `LoadExistingFiles()` properly extracts back definition from translation.txt
-   - Verify the split on "=" correctly extracts the part after the equals sign
-   - Confirm the value is actually the Bulgarian definition, not English
-
-2. **Translation field contains wrong value**
-   - When bg-bg card loads, does `a.translationEntry.SetText()` set the back definition or something else?
-   - Is the UI field showing the correct value?
-
-3. **Card type not detected correctly**
-   - Confirm `cardtype.txt` exists and contains "bg-bg"
-   - Verify `internal.LoadCardType()` works correctly
-
-4. **Field names confusion**
-   - The `translationEntry` field is named misleadingly
-   - For en-bg: it contains English translation
-   - For bg-bg: it contains Bulgarian definition
-   - Placeholder text should change to reflect this

-- `internal/gui/navigation.go` - Card loading logic (lines 364-460)
-- `internal/gui/generator.go` - Audio generation functions (lines 156-220)
-- `internal/gui/audio_player.go` - Audio playback implementation
-- `internal/processor/processor.go` - Batch processing audio generation
-
-### Test Case
-
-Use this batch input to create a test card:
-```
-котка == домашно животно
-```
-
-Then in the GUI:
-1. Navigate to the "котка" card
-2. Verify UI shows correct values
-3. Press `p` and listen - should hear "котка"
-4. Press `P` and listen - should hear "домашно животно"
-5. Press `a` - check console for "Generating front audio for 'котка'"
-6. Press `A` - check console for "Generating back audio for 'домашно животно'" (NOT "котка")
-
-### Notes
-
-- Batch processing works correctly (both audio files generated in correct locations as of Jan 21, 2025)
-- GUI playback buttons work correctly and show proper labels ("Front" / "Back")
-- The issue appears to be isolated to the `A` key regeneration logic
-- Audio file generation itself is not the problem - the issue is which TEXT is being passed to the generator
