Add "NRF52" as a device name prefix

At the top of the channel chat screen is an icon, indicating the
channel type.

Previously, the public icon was used correctly, but the
hashtag icon was used for all other types.

Now, consistent with the channels screen, we use the lock icon for
private channels, and the composite icons for community public &
community hashtag types.

The fix for private channels was trivial, as we can identify hashtag
channels by their name. Finding out whether a channel belongs to a
community is much more involved. All the hard-working code was copied
from channels_screen.dart. (I tried refactoring to reduce duplication,
but my results were complex and not worth it.)

Closes #432

- 繰り返し設定 → リピーターを自動追加 (contactsSettings)
- ホップの繰り返し → リピーターホップ (channelPath)

- 中継装置およびルームサーバーの設置場所 → リピーター/ルームサーバーの位置情報
- 繰り返し送信に関する情報 → リピーターに関する情報 (repeater_guest)

- 洪水 → フラッド (flood routing terminology)
- リピーター → リピータ (consistent katakana without long vowel)
- 中継局 → リピータ
- 繰り返し送信装置 → リピータ
- オフグリッド...の繰り返し → オフグリッドリピータ
- 最大浸水範囲の回数 → フラッドパケットの最大ホップ数
- インバウンドフラッパケット → インバウンドフラッドパケット (typo fix)
- ルーティングループに見えるような、洪水パケットを送信する → ルーティングループを検知する
- カスタムパスには、メッセージを中継できる中間地点が必要です → リピータが必要です
- ワンホップでの広告放送（中継なし）→（リピータなし）
