feat: add catchup and unpaired reminder notifications

Add automatic push notifications for behind partners (escalating: 24h then
every 3 days) and daily unpaired user reminders. Includes edge functions,
migrations, notification preference toggles, and UI improvements to pairing
and swipe screens.

+## Question Types
+
+Every question has a `question_type` that determines how partners interact with it.
+
+### `swipe` (default) - Yes/No/Maybe Proposal
+The classic Sauci format. Partners swipe yes, no, or maybe. Matches are created when both answer positively.
+
+- Can be **symmetric** (partner_text = NULL) or **asymmetric** (with partner_text + inverse pair)
+- Example: "Give your partner a back massage"
+
+### `who_likely` - "Who's More Likely To..."
+Partners each pick who they think is more likely. Fun, lighthearted conversation starters.
+
+- **ALWAYS symmetric** — partner_text = NULL, no inverse needed
+- Format: "Who is more likely to [activity/trait]?"
+- Match created when both answer
+- Examples:
+  - "Who is more likely to cry during a movie?"
+  - "Who is more likely to plan a surprise date?"
+  - "Who is more likely to fall asleep first?"
+  - "Who is more likely to forget an anniversary?"
+
+### `audio` - Voice Recording Prompt
+Partners record a voice message in response to a prompt. Great for confessions, storytelling, impressions, compliments.
+
+- **ALWAYS symmetric** — partner_text = NULL, no inverse needed
+- `config`: `{"max_duration_seconds": 60}`
+- Format: prompts that invite a natural spoken response
+- Examples:
+  - "Record your best impression of your partner"
+  - "Describe your favourite memory together"
+  - "Say something you've never told your partner"
+  - "Sing a song that reminds you of your partner"
+
+### `photo` - Photo Prompt
+Partners take or share a photo. Great for selfies, throwbacks, creative challenges.
+
+- **ALWAYS symmetric** — partner_text = NULL, no inverse needed
+- No special config needed
+- Format: prompts that invite a visual response
+- Examples:
+  - "Share a photo from your camera roll that makes you think of your partner"
+  - "Take a selfie showing how you feel right now"
+  - "Share a screenshot of your last text about your partner"
+  - "Show the view from where you are right now"
+
+### Type Distribution
+
+For a standard 30-question pack, aim for roughly:
+- **20-22 swipe** questions (the core experience)
+- **4-5 who_likely** questions
+- **2-3 audio** questions
+- **2-3 photo** questions
+
+Adjust based on the pack's theme. A "Getting to Know You" pack might lean heavier on who_likely and audio. An explicit pack might be mostly swipe.

 ## Question Structure
 
 Each question has:
 - `text` - What Partner A sees
-- `partner_text` - What Partner B sees (can be NULL)
-- `intensity` - 1-5 scale
+- `partner_text` - What Partner B sees (NULL for symmetric questions and all non-swipe types)
+- `intensity` - 1-5 scale (for backend filtering, not shown in UI)
+- `question_type` - `swipe`, `who_likely`, `audio`, or `photo`
+- `config` - JSONB for type-specific settings (e.g., `{"max_duration_seconds": 60}` for audio)
 - `allowed_couple_genders` - Which couple types see this (NULL = all)
 - `target_user_genders` - Which gender initiates (NULL = any)
 - `required_props` - Physical items needed (NULL = none)
-- `inverse_of` - UUID of primary question if this is an inverse (NULL for primary/symmetric)
+- `inverse_of` - UUID of primary question if this is an inverse (NULL for primary/symmetric/non-swipe)

 **IMPORTANT:**
 - Inverse pairs are NOT duplicates. When one question's `text` matches another's `partner_text`, they form a valid inverse pair. This is intentional and required - do not flag or remove these as duplicates.

-Most categories should have 3-5 packs that progress in intensity:
-
-### Example: Toy Time
-1. **Starting Out** (intensity 3-4) - Basic vibrators, blindfolds, simple toys

-
-### Example: Long Distance
-1. **Staying Close** (intensity 1) - FaceTime, voice notes, gaming together
-2. **Missing You** (intensity 2) - Flirty texts, missing each other, anticipation
-3. **Private Line** (intensity 3-4) - Sexting, phone sex, explicit photos
-4. **Total Control** (intensity 4-5) - Remote toys, edging, power dynamics
-
-### Example: Public Thrills
-1. **Testing the Waters** (intensity 2-3) - Whispers, secret touches, stolen kisses
