feat: UI polish round 2

[dmnyc]

Summary

Zap Dialog

• Remove message text from preset chips; show small message icon hint instead
• Pre-fill message field when selecting a preset, clear it when switching to a preset without one
• Move save button into the custom amount flow (appears below amount input when valid)
• Sort all presets by amount ascending
• Flatten chip layout from Column to single Row for consistent height

Global Bolt/Bitcoin Icon Toggle

• Wallet nav drawer icon respects the bolt/bitcoin setting
• Lightning address icon in drawer header and user profile respects the toggle
• Profile header zap button respects the toggle
• Increase unselected toggle icon alpha from 0.4 to 0.7 for better contrast across themes

NIP-05 Verification

• Fix case-sensitive NIP-05 JSON key lookup — servers returning capitalized names (e.g. "Blockstream" vs "blockstream") were incorrectly flagged as impersonators
• Extract shared Nip05Badge composable with self-contained collectAsState() subscription so it recomposes reliably in all contexts (feed, quoted notes, profile, notifications, search)
• Differentiate verification failure states:
  • Impersonator (pubkey mismatch): grey text + red cancel circle icon — permanent warning
  • Error (server unreachable): faded grey text, no icon — temporary, not actionable
  • Verified: orange/primary checkmark circle — unchanged
• Pass nip05Repo to all NoteActions constructors (was missing in 6 places: UserProfileScreen, NotificationsScreen ×2, Navigation DM/DM-group/group-room, SearchScreen)
• Hide nip05 field entirely for blank identifiers

Zap Animations

• Replace hand-drawn bolt paths with the actual ic_bolt vector in both LightningAnimation and ZapBurstEffect
• LightningAnimation: smooth pulse + scale breathing instead of rapid jittery flicker
• ZapBurstEffect: bolt icon particles radiating outward with staggered ease-out instead of jagged lightning strokes
• Fix bolt aspect ratio to 14×22dp to prevent horizontal stretching

Action Bar

• Replace reply arrow icon with comment bubble (ModeComment) at 22dp

Follow Indicator

• Remove follow badge circle from profile picture avatar
• Add subtle inline checkmark next to display name (PostCard and GalleryCard)

Emoji Reactions

• When user opens emoji library via "+" in reaction popup, selecting an emoji now both adds it to the quick list AND sends the reaction in one action
• Applied across all EmojiLibrarySheet call sites (feed, profile, thread, article, notifications, DMs, groups)

Wallet & Auth

• Hide recovery phrase behind full-opacity tap-to-reveal overlay with eye icon
• Persist balance hidden state to SharedPreferences (survives app restart)
• Fix balance unit pills wrapping on small screens (tighter padding, smaller text, maxLines=1)
• Add superellipse squircle shape to sign-in logo for non-black themes
• Remove quotation marks from zap messages in TopZapperBanner

Interface Settings

• Collapse custom color picker behind tap-to-expand section (prevents accidental touches while scrolling)

Navigation & Layout

• Fix thread scroll-to-reply: fall back to getReplyTarget when getRootId returns null; wait for list layout before scrolling; clear scroll target after success
• Auto-scroll drawer to bottom when Settings menu expands
• Add statusBarsPadding to drawer content so profile picture doesn't overlap phone UI
• Remove bottom inset gap from drawer by zeroing window insets
• Fix black gap between content and bottom nav bar by applying NavigationBarDefaults.windowInsets

Test plan

• Verify zap dialog preset chips show amount + message icon, sorted ascending
• Custom amount → enter value → "Save" appears below input → saves and selects
• Toggle bolt/bitcoin in Interface settings → verify all icons update (drawer, profile, action bar)
• NIP-05 with capitalized server keys (e.g. Blockstream) verifies correctly
• NIP-05 impersonator: grey text + red ⊘ icon
• NIP-05 error: faded grey text, no icon
• NIP-05 verified: orange/primary checkmark circle
• Consistent across posts, quoted notes, profile, and notifications
• Send a zap → observe smooth pulse animation during send, bolt particle burst on confirmation
• Comment bubble icon visible in action bar row, consistent size with other icons
• Open emoji library from reaction popup "+" → select emoji → verify it both adds and reacts
• View recovery phrase → verify hidden behind overlay → tap to reveal
• Hide wallet balance → restart app → verify stays hidden
• Check balance unit pills don't wrap on small screens
• Tap a reply in feed → thread scrolls to that reply, not the root
• Open drawer → profile picture sits below status bar
• Expand Settings in drawer → auto-scrolls to reveal items
• No black gap between content and bottom nav bar
• Sign-in screen logo has squircle shape on non-black themes
• Color picker in Interface settings collapsed by default, expands on tap
