Restore lost guide content and broker access references

[MrAlders0n]

This restores useful community guidance that was trimmed during the site overhaul, keeps the overhaul's safety and verification structure, and folds the MQTT broker reference work from #88 into one reviewable change.

Restored and updated

• Restores the bilingual wire-connector reference and adds it to the Devices & Builds navigation.
• Adds the bilingual experimental 1 W solar repeater guide to the navigation while keeping its electrical, RF, battery, and site-review gates.
• Restores the companion and antenna recommendations, prices, local suppliers, connector warnings, and DIY companion example.
• Restores the MeshCore project-split notice and expanded device-role guidance.
• Restores the bilingual MQTT broker administrator contacts.
• Documents the current read-only subscriber inventory, including hansimgamr for Quinte Mesh.

Corrections made during review

• Describes dedicated repeaters as the recommended routing backbone without incorrectly claiming that room servers can never repeat.
• Corrects the room-server history wording to 32 unseen messages.
• Makes clear that the WisMesh Tag ships with Meshtastic and must be flashed with MeshCore before use.
• Limits replacement-antenna advice to devices with removable antennas.
• Removes stale claims about a cheaper unflashed T-Echo, guaranteed duty treatment, and the T-Deck Plus being designed for MeshCore.
• Replaces the unfinished-page label on the connector reference and names connector pitch correctly.

The role and firmware corrections were checked against the current MeshCore FAQ, MeshCore configurator, official MeshCore hardware/flasher page, and RAK WisMesh Tag documentation.

Validation

• node --test tests/content/*.test.mjs — 74 passed
• python -m unittest discover -s tests/content — 14 passed
• strict bilingual site build and built-link validation — 129 pages and 13,170 local references passed
• Chromium browser suite — 66 passed, 5 intentionally skipped
• git diff --check — clean

PR #88 is included in this branch and can be closed once this push is confirmed.

I found three accuracy issues that should be corrected before this is merged:

1. The role matrix and details say only dedicated repeaters route traffic, but current room-server firmware can repeat. The official FAQ says this is supported but not recommended, and the official configurator currently exposes the room-server Repeat setting. Dedicated repeaters should be described as the recommended backbone, not the only devices capable of forwarding traffic.

   • https://github.com/meshcore-dev/config.meshcore.io/blob/main/index.html#L437-L445

2. The WisMesh Tag is described as pre-flashed for instant use. RAK documents that it ships with Meshtastic, so a MeshCore reader still needs to flash the current MeshCore companion firmware.

   • https://meshcore.io/

3. The antenna warning says every listed companion needs an upgraded antenna, but the T1000-E and WisMesh Tag use internal antennas; RAK also warns that opening the Tag damages the enclosure. The advice should be limited to devices with replaceable antennas.

I also found a few smaller stale purchasing claims (the T-Echo firmware variant, guaranteed duty treatment, and “built with MeshCore in mind” wording for the T-Deck Plus). I’m correcting these in English and French and folding #88 into this branch so the repository has one reviewable PR.

Review follow-up: the accuracy issues I called out above are fixed in 109d241, and PR #88 is now fully folded into this branch and closed.

The unified PR now restores the bilingual guide content, corrects room-server/client-repeat wording, fixes the WisMesh Tag and sealed-antenna guidance, removes stale purchase claims, restores the broker administrator contacts, and lists hansimgamr for Quinte Mesh.

Verified on the exact pushed commit:

• validation: passed
• Lighthouse: passed
• hosted browser suite: passed
• local content tests: 74 passed
• local Python content tests: 14 passed
• strict bilingual build/link check: 129 pages and 13,170 references passed
• local Chromium suite: 66 passed, 5 intentionally skipped
• final repository guard: clean worktree, exact local/remote SHA, no blockers

This is ready for a fresh maintainer review.
