Add sending domain update and company info commands

[mklocek]

Changes

Adds the sending-domain update command and the nested company_info commands, which exist in the API (per email-sending.openapi.yml) but were missing from the CLI.

• domains update — PATCH on the domain with --open-tracking, --click-tracking, --tracking-opt-out, --auto-unsubscribe-link and --inbound-enabled.
• company-info get / create / update — new command group on /api/domains/{id}/company_info. The account is resolved from the API token, so these commands do not call config.RequireAccountID(), following the emailcampaigns package. Responses unwrap the data envelope.
• Partial updates — both update commands send only the flags the user actually passed, via cmd.Flags().Changed, so an update cannot clear unrelated fields. Both also reject an update with no attribute flags rather than sending an empty wrapper, matching emailcampaigns update.
• Output — domains update renders an extended column set so all five settings it can write are visible; company-info columns cover every field the API returns, including the privacy-policy and terms-of-service URLs. CompanyInfo fields are *string so unset values render as empty cells.
• create validation — the six spec-required fields are checked in a fixed order, so the reported missing flag is deterministic.
• Tests / README — 10 new tests covering both groups (request-body shape on the PATCH paths, missing-required-flag and empty-update cases), plus the command-table rows and usage examples.

Company-info API commands internal/commands/companyinfo/*.go, internal/commands/companyinfo/companyinfo_test.go	Added GET, POST, and PATCH handlers with flag validation, selective payloads, formatted output, and HTTP test coverage.
Sending-domain tracking updates internal/commands/domains/*, README.md	Added tracking fields and the domains update command. Registered the command, added validation and PATCH tests, and documented the new commands.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 00739

The PR adds localized CLI commands, but company-info output currently hides two supported values, an empty update can issue an unnecessary PATCH request, and test code has lint-reported unchecked JSON errors. The change is mergeable with explicit owner awareness and follow-up on these bounded issues.

In `@internal/commands/companyinfo/companyinfo_test.go`:
- Line 75: Check and handle errors from every json.NewEncoder.Encode and
json.Unmarshal call in the test handlers, including the occurrences in
companyInfoPayload-related handlers and the additional indicated locations.
After a failed json.Unmarshal, return immediately from the handler so assertions
do not operate on incomplete request data.

In `@internal/commands/companyinfo/companyinfo.go`:
- Around line 26-35: Add privacy-policy and terms-of-service URL columns to
companyInfoColumns so default table output displays the privacy_policy_url and
terms_of_service_url fields returned by company-info get, create, and update
operations.

In `@internal/commands/companyinfo/update.go`:
- Around line 62-65: Before the Patch call in the company-info update command,
validate that at least one mutable company-info flag was supplied, including
when only --domain-id is provided. Return a clear validation error and skip the
API request when companyInfoFields is empty; preserve the existing Patch
behavior for non-empty updates.
