tiennm99 e5125fcd93 feat(blacklist): add per-topic text deny-list with whitelist exceptions ...

Six public commands let any member of a chat curate two lists of text and
ask whether a given text is blocked: /blacklist_add, /blacklist_del,
/whitelist_add, /whitelist_del, /blacklist_rules and /blacklist_check.

The module is passive. It never reads ordinary chat messages and never
deletes, warns or restricts anyone; the lists stay inert until
/blacklist_check asks about a specific text.

Scope is one forum topic, keyed (Chat.ID, MessageThreadID) and gated on
IsTopicMessage so a reply chain in a plain supergroup does not become its
own unreachable scope. A plain group, a DM and a forum's General topic all
resolve to one chat-wide list.

Matching is substring, after NFKC composition, case folding and whitespace
collapse. Diacritics stay significant, so ma, má and mà are three entries.
A whitelist entry rescues a blacklist match only when it spans that match,
which is what keeps "I met an assassin, dumbass" blocked.

Entry text is percent-encoded before it becomes a storage key, since keys
forbid '/' and cap at 1500 bytes, and is capped at 200 bytes before and
after normalization because NFKC can expand as well as contract.

/blacklist_rules reads each list with Scan, so listing costs one round trip
per list rather than a Get per entry.
