fix(gotjunk): Long-press should update defaults, not auto-save

[Foundup]

Critical UX Fixes

Addresses two major issues reported by user testing:

Issue #1: Long-Press Auto-Saves (Broken Flow)

Problem:

• User long-presses Discount → selects 50% → item IMMEDIATELY saves
• No way to review selection before confirming
• Cannot change mind after long-press

Root Cause:

const handleDiscountSelect = (percent: number) => {
  setDiscountPercent(percent);
  onClassify('discount', percent, undefined); // ← PROBLEM: auto-saves
};

Solution:

const handleDiscountSelect = (percent: number) => {
  setDiscountPercent(percent);
  setDiscountSheetOpen(false);
  localStorage.setItem('gotjunk_default_discount', percent.toString());
  // Haptic feedback only - NO onClassify call
};

New Flow:

1. User long-presses Discount → action sheet opens
2. User selects 50% → action sheet closes, modal shows "50% OFF"
3. User taps Discount button → confirms and saves item
4. User can change mind by long-pressing again or selecting different classification

Issue #2: Defaults Don't Persist

Problem:

• User sets discount to 50% via long-press
• Next photo capture → modal resets to 75% (hardcoded default)
• User must long-press and re-select 50% every single time

Root Cause:

const [discountPercent, setDiscountPercent] = useState(75); // Always 75%
const [bidDurationHours, setBidDurationHours] = useState(48); // Always 48h

Solution:

const [discountPercent, setDiscountPercent] = useState(() => {
  const saved = localStorage.getItem('gotjunk_default_discount');
  return saved ? parseInt(saved, 10) : 75; // Load saved or default
});

Persistence:

• gotjunk_default_discount → stores 25, 50, or 75
• gotjunk_default_bid_duration → stores 24, 48, or 72
• Loaded on modal mount (lazy initialization)
• Persists across sessions

UX Flow (Fixed)

First Capture (No Saved Preferences):

1. User captures photo → modal shows with 75% OFF / 48h (fallback defaults)
2. User long-presses Discount → action sheet opens
3. User selects 50% → action sheet closes, modal shows "50% OFF"
4. User taps Discount → item saved with 50% discount
5. Value saved to localStorage

Second Capture (Has Saved Preferences):

1. User captures photo → modal shows with 50% OFF (loaded from localStorage)
2. User taps Discount → item saved with 50% (no need to long-press again)

Changing Default:

1. User captures photo → modal shows with 50% OFF (current saved default)
2. User long-presses Discount → action sheet opens
3. User selects 75% → action sheet closes, modal shows "75% OFF"
4. User taps Discount → item saved with 75% discount
5. New value (75%) saved to localStorage for future captures

Auto-Posting Investigation

Original Report: "Sometimes I don't get an option when taking a pic and it automatically posts"

Root Causes Identified & Fixed:

1. ✅ Framer Motion gesture conflict (PR HOTFIX: Classification modal tap gestures not working #32) - whileTap was consuming tap events
2. ✅ Long-press auto-save (this PR) - Action sheet selections were calling onClassify immediately
3. ✅ No user confirmation - Item saved without explicit tap-to-confirm

Prevention:

• Removed all auto-save paths from action sheet handlers
• User must explicitly tap classification button to save
• Modal only closes on explicit save or cancel

Technical Changes

ClassificationModal.tsx:

• Updated handleDiscountSelect: Remove onClassify call, add localStorage save
• Updated handleBidSelect: Remove onClassify call, add localStorage save
• Updated useState initialization: Lazy load from localStorage
• Added haptic feedback on selection (vibrate pattern)

localStorage Keys:

• gotjunk_default_discount: "25" | "50" | "75"
• gotjunk_default_bid_duration: "24" | "48" | "72"

Haptic Feedback:

• Pattern: [10, 50, 10] (short buzz, pause, short buzz)
• Fires on action sheet selection (confirms visual feedback)

Testing Required

Test 1: Long-Press Flow

• Capture photo → modal opens
• Long-press Discount → action sheet opens
• Select 50% → action sheet closes, modal shows "50% OFF"
• Modal STILL OPEN (not auto-saved)
• Tap Discount → item saved

Test 2: Defaults Persist

• Set discount to 50% via long-press, tap to save
• Capture another photo → modal opens with 50% OFF (not 75%)
• Tap Discount → saves with 50%
• Repeat 3x → always shows 50% as default

Test 3: Changing Defaults

• Current default: 50%
• Long-press Discount → select 25% → modal shows "25% OFF"
• Tap Discount → saves with 25%
• Next capture → modal shows 25% OFF (new default)

Test 4: Bid Duration

• Long-press Bid → select 72h → modal shows "72h"
• Tap Bid → saves with 72h duration
• Next capture → modal shows 72h as default
