Telegram Allowlist Hardening

PR: #216
Summary
Telegram allowlists now accept telegram: and tg: prefixes case-insensitively, and tolerate
accidental whitespace. This aligns inbound allowlist checks with outbound send normalization.
What changed
- Prefixes
telegram:andtg:are treated the same (case-insensitive). - Allowlist entries are trimmed; empty entries are ignored.
Examples
All of these are accepted for the same ID:
telegram:123456TG:123456tg:123456
Why it matters
Copy/paste from logs or chat IDs often includes prefixes and whitespace. Normalizing avoids false negatives when deciding whether to respond in DMs or groups.
