Fix Yemen cities data: correct timezones, remove duplicates, and complete state coverage

[Copilot]

Following the addition of the missing Ad Dali' governorate in PR #1156, this PR addresses critical data quality issues discovered in Yemen's cities dataset during comprehensive review.

Issues Fixed

1. Incorrect Timezone (All 339 Cities)

Problem: Every city in Yemen had timezone "Europe/Moscow" instead of the correct "Asia/Aden".

Impact: All 339 cities now use the correct IANA timezone for Yemen (Asia/Aden, UTC+3).

2. Duplicate City Entry

Problem: "Az Zahir" (الظاهر) appeared twice with conflicting data:

• ID 130803 in Al Jawf (JA) at coordinates 16.33°N, 44.52°E
• ID 130804 in Al Bayda' (BA) at coordinates 13.99°N, 45.42°E
• Both entries shared WikiData ID Q20423895

Resolution: Research confirmed WikiData Q20423895 refers to Az Zahir district in Al Bayda' Governorate. Removed the incorrect duplicate (ID 130803) and kept the accurate entry (ID 130804).

3. Sanaa City Misassignment

Problem: Sanaa (صنعاء), Yemen's capital city, was assigned to Sana'a Governorate (YE-SN, state_id: 1236) instead of the capital municipality.

Correction: Reassigned Sanaa (ID 130964) to Amanat Al Asimah municipality (YE-SA, state_id: 1232). This aligns with WikiData Q2471 and the administrative structure where Amanat Al Asimah is the special capital municipality containing Sanaa city, similar to Washington D.C. or Brasília.

4. Missing Cities for New Governorate

Problem: The newly added Ad Dali' governorate (YE-DA, state_id: 5467 from PR #1156) had no cities assigned.

Addition: Added Ad Dali' city (الضالع) as the governorate's capital with WikiData Q7308711.
