feat(telegram): expand channel coverage with 11 new OSINT sources

[koala73]

Summary

• Adds 9 channels to the full set: ReportingFromUkraine, middleeastobserver, MiddleEastEye, IranIntl_En, syriahr, dragonwatch, indopacificnews, sahelwatch, sudanwarmonitor
• Adds 2 channels to the tech set: vxunderground, falconfeeds
• Replaces iranintltv with the correct English-language handle IranIntl_En
• Expands coverage to two previously absent regions: Asia-Pacific and Africa

Region	New channels
Ukraine	ReportingFromUkraine
Middle East	middleeastobserver, MiddleEastEye, IranIntl_En, syriahr
Asia-Pacific	dragonwatch, indopacificnews
Africa	sahelwatch, sudanwarmonitor
Cyber (tech)	vxunderground, falconfeeds

Test plan

• Verify all new handles resolve on Telegram before relay deploys
• Confirm IranIntl_En is the English channel (vs Persian IranIntl)
• Check relay picks up new channels from data/telegram-channels.json on next poll cycle
• Validate Asia/Africa regions display correctly in the Telegram Intel panel topic filter

Greptile Summary

This PR expands the curated Telegram channel list by adding 10 net-new channels (8 to full, 2 to tech) and replacing the stale iranintltv handle with the correct English-language handle IranIntl_En. It also introduces two new region values — asia and africa — which the relay passes through as string tags and does not validate against an enum, so they work at runtime without any code changes.

Key observations:

• All new entries are structurally consistent with the existing schema (required fields present, tier/maxMessages values aligned with comparable channels).
• The updatedAt timestamp is correctly bumped to 2026-03-29T00:00:00Z.
• Four new full-set channels (middleeastobserver, MiddleEastEye, dragonwatch, indopacificnews) use \"topic\": \"geopolitics\", which has no corresponding entry in TELEGRAM_TOPICS (src/services/telegram-intel.ts). Items from these channels will only appear under the "All" tab — not under any specific topic filter — consistent with a pre-existing pattern but amplified by this PR.
• The PR title states "11 new OSINT sources", but one of the 11 entries (IranIntl_En) is a replacement for iranintltv, not a net-new source; the accurate new-channel count is 10.

Confidence Score: 5/5

Safe to merge — all changes are purely additive data edits with no logic changes; the single finding is a pre-existing design pattern.

All findings are P2. The geopolitics topic tab gap pre-dates this PR and doesn't break any existing functionality — channels without a matching tab remain accessible under "All". No runtime errors, data loss, or breaking changes are introduced. The JSON structure is valid and consistent.

No files require special attention; src/services/telegram-intel.ts is worth a follow-up to add a geopolitics filter tab if content discoverability matters.

Important Files Changed

Filename	Overview
data/telegram-channels.json	Adds 8 new channels to full set and 2 to tech set, replaces iranintltv with IranIntl_En, and bumps updatedAt. All entries are structurally valid; four new channels use topic: "geopolitics" which has no tab in TELEGRAM_TOPICS, making them only visible in the "All" filter (pre-existing pattern but amplified).
