Port 4 missing Telegram forum/topic features from TypeScript OpenClaw:
1. Thread-not-found fallback: retry sends without message_thread_id when
a topic is deleted (sendHTML, sendPhoto, sendVideo, sendAudio,
sendDocument, stream flush).
2. Per-topic config: hierarchical config resolution (global → wildcard
group "*" → specific group → specific topic) for groupPolicy,
requireMention, allowFrom, enabled, skills, systemPrompt.
New TelegramGroupConfig/TelegramTopicConfig structs, resolveTopicConfig()
with 10 unit tests.
3. DM topic support: preserve message_thread_id in private chats for
session isolation. New BuildDMThreadSessionKey, parseRawChatID handles
🧵 suffix.
4. createForumTopic agent tool: ForumTopicCreator interface decoupled
from telego, lazy bot resolution via channel manager.
5. Web UI: structured group/topic config form with tri-state booleans
(Inherit/Yes/No), nested collapsible group and topic entries.
Also fix: forum group pairing reply and approval notification now
correctly set MessageThreadID so messages land in the right topic.
Send() extracts threadID from localKey suffix as fallback for cases
where metadata is absent (e.g. pairing approval via SendToChannel).
