feat(amplitude): add data/amplitude with complete domain list (#3997)

* feat: add data/amplitude with complete domain list

Add comprehensive Amplitude domain list based on official docs
(https://amplitude.com/docs). Domains tagged @ads are analytics/tracking
endpoints; the rest are product/API/dashboard domains left untagged.

@ads domains (tracking/analytics):
- api.amplitude.com, api2.amplitude.com, api.eu.amplitude.com:
  event ingestion endpoints (HTTP API v2/Batch).
  https://amplitude.com/docs/apis/analytics/http-v2
  https://amplitude.com/docs/apis/analytics/batch-event-upload
- regionconfig.amplitude.com, regionconfig.eu.amplitude.com:
  dynamic configuration endpoints used by SDKs to pick the best
  ingestion server; listed in the iOS SDK privacy manifest under
  NSPrivacyTrackingDomains.
  https://amplitude.com/docs/sdks/analytics/ios/ios-sdk
  https://amplitude.com/docs/sdks/dynamic-configuration
- api-sr.*, sr-client-cfg.*, api-secure.* (US/EU):
  Session Replay capture, config and upload endpoints.
  https://amplitude.com/docs/sdks/session-replay
- gs.*, engagement-static.*, assistant-api.* (US/EU):
  Guides and Surveys delivery/tracking domains.
  https://amplitude.com/docs/guides-and-surveys/proxy
- cdn.amplitude.com, cdn.eu.amplitude.com:
  CDN serving the analytics SDK scripts to end users.
  https://amplitude.com/docs/sdks/analytics/browser/browser-sdk-2
- lab.amplitude.com, lab.eu.amplitude.com:
  covers Experiment evaluation endpoints (api.lab, flag.lab,
  stream.lab, cohort.lab, cohort-v2.lab) via subdomain match.
  https://amplitude.com/docs/apis/experiment/experiment-evaluation-api

Non-ads domains (product/API/UI):
- analytics.amplitude.com / analytics.eu.amplitude.com: web app +
  Dashboard REST API. https://amplitude.com/docs/apis/analytics/dashboard-rest
- core.*: SCIM API. https://amplitude.com/docs/apis/analytics/scim
- data-api.*: Lookup Table API. https://amplitude.com/docs/apis/analytics/lookup-table-2
- privacy.*: User Privacy API. https://amplitude.com/docs/apis/analytics/user-privacy-v2
- profile-api.*: User Profile API. https://amplitude.com/docs/apis/analytics/user-profile
- experiment.*: Experiment management API/UI.
  https://amplitude.com/docs/apis/experiment
- mcp.*: Amplitude MCP server. https://amplitude.com/docs/analytics/amplitude-mcp
- data.*: Amplitude Data UI/API. https://amplitude.com/docs/data
- app.*, eu.amplitude.com, recommend.amplitude.com, amplitude.com:
  dashboard/login and marketing pages.

Other changes:
- category-ads-all: add include:amplitude so @ads entries are included.
- unity: remove api2.amplitude.com @ads (now covered by data/amplitude).

* refactor: move amplitude ads domains to category-ads

- data/amplitude: remove untagged redundant subdomains (already matched
  by amplitude.com), keep only the root domain and @ads subdomains
- data/category-ads: add include:amplitude @ads
- data/category-ads-all: remove include:amplitude

data/unity
