fix: drop domain from computed remote name when subdomain present (#22376)

## Context

Closes twentyhq/core-team-issues#2619

When adding a remote with `yarn twenty remote:add` and a URL like
`https://martin-s-workspace.twenty.com`, the computed remote name ended
up as `martin-s-workspace-twenty-com`. The apex domain (`twenty.com`)
should be dropped when a subdomain is present, so the name should be
`martin-s-workspace`.

## What changed

- Extracted `deriveRemoteName` from `remote/index.ts` into its own
module `remote/derive-remote-name.ts`.
- When the host has a subdomain (more than two labels), only the
subdomain labels are used (joined with dashes) — the apex domain is
dropped.
- Hosts with no subdomain keep the full host (`twenty.com` →
`twenty-com`).
- Single-label hosts like `localhost` are preserved.
- IPv4 addresses are kept intact (`127.0.0.1` → `127-0-0-1`).
- Invalid URLs still fall back to `remote`.

## Tests

Added `derive-remote-name.spec.ts` covering subdomain, multi-label
subdomain, apex-only host, `localhost`, IPv4, and invalid-URL cases. All
6 pass.
