feat(apply): verify posting source host against installed portals and known ATS apexes (#431) (#467)

- Add source host verification rule to apply.md Step 1 before drafting
- Check posting URL host against installed portals and six official ATS apexes
- Enforce fail-closed look-alike parsing (prefix, suffix, userinfo spoofing)
- Plainly flag unverified third-party hosts in evaluation output
- Add tests/test_apply_host_check.py and update CHANGELOG.md

If the posting specifies a city, add `--city "<City>"` to narrow results. Parse the JSON output and include the salary benchmark in the evaluation. If the tool is not configured or returns an error, skip the salary benchmark.
### Source Host Verification (when input is a URL)
Before proceeding to drafting, inspect the posting URL's hostname to verify provenance (#431). Classify the host into one of three categories:
1. **Installed portal board:** the host matches any configured job portal in `.agents/skills/` (e.g. `jobindex.dk`, `linkedin.com`, `jobnet.dk`, `jobbank.dk`, `jobdanmark.dk`, `freehire.me`, or any portal added by `/add-portal`).
2. **Known official ATS apex:** the host matches or is a valid subdomain of one of the six standard ATS domains:
- `greenhouse.io`
- `lever.co`
- `myworkdayjobs.com` (or `workday.com`)
- `ashbyhq.com`
- `smartrecruiters.com`
- `workable.com`
*Look-alike parsing:* the host must match the apex exactly or end with `.<apex>`. Look-alike prefix tricks (e.g. `evil-greenhouse.io`), suffix spoofing (e.g. `job-boards.greenhouse.io.evil.com`), userinfo tricks (`https://greenhouse.io@evil.com/`), and unfamiliar subdomains fail closed and must not be classified as an official ATS.
3. **Neither (Unverified host):** name the host plainly in the evaluation output as unverified (`⚠ Unverified source host: <hostname> - not an installed portal board or known ATS apex`). Alert the user to verify the employer and link legitimacy before committing time and tokens to drafting.
Present the evaluation to the user with:
1. **Skills match** - which required/preferred skills match vs. gaps
2. **Experience match** - how work history maps to the role
3. **Behavioral/culture match** - how behavioral profile fits the role/company culture
4. **Salary benchmark** - salary index for the company (if available)
5. **Overall fit score** and recommendation (strong fit / moderate fit / weak fit)
1. **Source host verification** - installed portal board, official ATS, or ⚠ unverified source host (named plainly)
2. **Skills match** - which required/preferred skills match vs. gaps
3. **Experience match** - how work history maps to the role
4. **Behavioral/culture match** - how behavioral profile fits the role/company culture
5. **Salary benchmark** - salary index for the company (if available)
6. **Overall fit score** and recommendation (strong fit / moderate fit / weak fit)
After presenting the evaluation, ask the user:
> "Should I proceed with drafting the CV and cover letter for this role?"
