refactor(hachidori): drop the Docker management upload for character dictionaries

Every supported host now takes dictionary ZIPs over the link, so remove
the port 8780 upload, its hachidori.externalHostManagementUrl override and
the hachidori config section. A linked host without linked-import-v1 now
reports the update or manual-import fix.

 Each backend stores its own dictionaries and mining settings. `yomitan.externalProfilePath` applies only to Yomitan. See [Hachidori setup](./usage.md#hachidori-setup) before switching an existing installation.
 
-`hachidori.externalHostManagementUrl` overrides the management origin that character dictionaries upload to when Hachidori is linked to a Docker host. Leave it empty to use the linked host's machine on the Docker management port. Set it only for a non-default `ADMIN_PORT` or a reverse proxy, and use the management port, not the sharing or dictionary API port. See [Hachidori setup](./usage.md#hachidori-setup).

 ### Logging
 
 Log files are named by date (`app-YYYY-MM-DD.log`, `launcher-...`, `mpv-...`). Log export writes a sanitized copy and leaves the originals alone.

 While linked, dictionaries and dictionary settings come from the host. Anki templates, pronunciation sources, custom buttons, and SubMiner's audio and image processing stay local. Frequency annotations use ranks returned with dictionary entries, and SubMiner asks the host for missing ones. Words with no matching definition entry may stay unranked even if a frequency dictionary lists them.
 
-SubMiner sends [character dictionaries](/character-dictionary) to the linked host over the link and replaces the previous one once the import succeeds, retrying while the host is busy. This needs Hachidori 0.2.3 or later on the host. With an older host, sync reports where the merged ZIP is so you can import it from that host's Hachidori settings.

-Docker hosts take the upload on their management port (8780) instead. If the host uses a different `ADMIN_PORT` or sits behind a reverse proxy, set `hachidori.externalHostManagementUrl` to its management origin, for example `"http://pve-main:9000"`. This is not the WebSocket sharing address. Browser hosts and local Hachidori do not need this setting.
