docs: feature Subtitle Edit FunASR integration

[LauraGPT]

Summary

• publish bilingual Subtitle Edit v5.2.0-beta2 setup and model-selection guides for Fun-ASR Nano and SenseVoice
• surface the 13.7K-star integration on both ecosystem pages and blog indexes
• use exact-tag engine sources for platform, language, and Q4/Q8/F16 size claims
• fix the ecosystem navigation on mobile so the fixed header no longer wraps over content
• add regression coverage for routes, evidence links, local media, and model facts

Verification

• python3 -m pytest web-pages/product-site/tests -q --tb=short -> 61 passed
• python3 -m pytest tests/test_check_funasr_website_static.py -q --tb=short -> 25 passed
• product-site build -> 23 product pages
• output validator -> 98 pages
• visual checks at 1440px and 390px for both languages, including image decode, overflow, fixed navigation, table, and ecosystem card layout

The guide explicitly labels the release as beta and describes PR #13063 as a CrispASR runtime update plus SenseVoice Metal verification, not as the initial backend integration.
