chore: drop HOST overrides, move known issue to docs, tidy comments and gitignores

- Remove HOST=${SERVICE_HOSTNAME} from code-server, code-server-lsio and paseo; hostname: alone sets the name
- Move SERVICE_HOSTNAME to the top of their .env.example to match compose order
- Drop the openclaw ARM64 Chromium note from its README; docs/openclaw covers it
- List CUSTOM_USER in webtop's setup step
- Trim reasoning from diun and paseo comments
- Delete stale gitea and gitea-mirror .gitignore files
- Add TODO.md for remaining naming and README issues

-`SERVICE_HOSTNAME` is used twice: as the container's `hostname:` and as the
-`HOST` variable inside it. Coolify injects `HOST=0.0.0.0` into every compose
-app, and zsh seeds `$HOST` and the `%m`/`%M` prompt escapes from that variable
-rather than calling `gethostname()` — so the prompt reads `0`, the first
-dot-separated field of `0.0.0.0`. code-server itself never reads `HOST` — it
-binds `[::]:8443` — so overriding it only affects the prompt. bash is
-unaffected; its `\h` uses the real hostname.
-
 `PUID`/`PGID` are pinned to `1000` in `compose.yml`; the `Dockerfile` depends
 on that (see [Storage](#storage)).
