fix(llc, ui, sample): more v10 QA fixes

[xsahil03x]

Summary

Follow-up QA pass on top of the v10 design refresh, plus the supporting SDK changes.

stream_chat

• Added debugCurrentPlatformOverride on StreamPlatformDetector so tests can simulate iOS / Android / web behavior without per-class overrides.

stream_chat_flutter

• Added StreamQuotedMessage and StreamQuotedMessageThemeData for the quoted-message preview, exposed through the component factory. Theme data carries the chrome (background, shape, side, margin, padding) and the trailing thumbnail (thumbnailShape, thumbnailSide, thumbnailSize).
• Adopted stream_core_flutter primitives:
  • Composer header attachments (link preview, reply / edit, voice recording) now use the new core.StreamMessageComposer* widgets.
  • StreamingMessageView switched to core.StreamMessageText; the local StreamMarkdownMessage widget and its export were removed (breaking — consumers should use the re-exported StreamMessageText).
  • StreamQuotedMessage, StreamChannelListItem and StreamQuotedMessageThemeData rebuilt on top of the shared core building blocks.
• Confirmation dialog polish:
  • Switched the affirmative action in the poll dialogs (suggest option, add comment, end vote, delete option) and StreamMessageActionConfirmationModal from the ghost StreamButton variant to solid, so it stands out from the ghost-secondary cancel.
  • StreamMessageActionConfirmationModal now honors its isDestructiveAction flag (the confirm action was previously rendered as destructive regardless).
• Removed the unused dialog widgets in lib/src/dialogs (ConfirmationDialog, DeleteMessageDialog, MessageDialog, ChannelInfoDialog) and their barrel. None were exported from the public library.
• Added StreamChatConfigurationData.reactionOverlap and StreamMessageReactions.overlap to control whether reactions overlap the message bubble edge. When unset, falls back to the platform-based default (overlap on mobile, no overlap on desktop and web).
• Capped StreamCommandAutocompleteOptions and StreamMentionAutocompleteOptions at fixed max heights (208 / 176) so the lists scroll internally instead of expanding to half the screen and overlapping the header.
• Hid the "Add an option" button in the poll creator when adding isn't allowed (an existing option is empty, or the max has been reached) — previously rendered as a disabled lookalike of an empty option row.
• Fixed StreamChannelListTile subtitle appearing centered when the channel had no messages yet — switched the inner column to crossAxisAlignment: start.
• Bumped the stream_core_flutter git ref.

sample_app

• Mirrored the new dialog button pattern in the sample-app confirmation dialogs (channel list, chat info, group info).
• Added a "Reaction Overlap" segmented row in the config screen alongside Type / Position.
• Removed the misleading auto-chevron on action rows in the channel detail / chat info screens — the chevron is now opt-in via explicit trailing for navigation rows only.
• Added the destructive Delete Group action to GroupInfoScreen for admins, mirroring the channel-list long-press sheet.
• Fixed the Edit Group sheet shrink-wrapping to the keyboard top edge; now fills the available height so there's breathing room above the keyboard.

repo

• gitignored devtools_options.yaml (auto-generated Flutter DevTools stubs).

Test plan

• Quote a message → quoted-message preview renders with the new chrome (rounded card, optional trailing thumbnail).
• Reply to / edit / record voice into a message → composer header attachments render the same as before.
• Trigger an AI streaming response → markdown still renders correctly via StreamMessageText.
• Open a poll → suggest option / add comment / end vote / delete option dialogs each show a solid affirmative button alongside a ghost cancel.
• Long-press a message → flag / delete confirmation modals: solid destructive confirm + ghost cancel.
• Sample-app confirmation dialogs (leave channel, delete channel from chat info / group info) match the new pattern.
• In the sample-app config screen, toggle Reaction Overlap between Default / Overlap / No Overlap and verify reactions render accordingly.
• GroupInfoScreen / ChatInfoScreen: navigation rows show a chevron, action rows (Leave / Delete / Block) do not.
• GroupInfoScreen as an admin: Delete Group appears below Leave Group; tapping shows a confirm dialog and pops to the channel list on success.
• Open the Edit Group sheet with the keyboard up → the text input has space above the keyboard.
• Type `/` in the composer with many commands → the list caps at 208px and scrolls internally without overlapping the header.
• Type `@` in the composer with many channel members → the list caps at 176px and scrolls internally.
• Open the Create Poll sheet → the "Add an option" button is hidden until you type in the existing option.
• Open the channel list with an empty channel → "No messages yet" is left-aligned under the title (not centered).
• CI goldens pass without further regen.
