fix(geo-data): correct country_id mismatch in states.csv and cities.csv

[YogeshK34]

Problem

states.csv contains a systematic country_id corruption affecting all countries from Germany onward (~148 countries). The country_code column is correct, but country_id values don't match the IDs in countries.csv — causing states of one country to be served under another.

Example:

File	name	country_id (before)	country_code	Actual country
states.csv	Andhra Pradesh	99	IN	Hong Kong (99) ≠ India (102)

This means selecting India in the UI returned Iran's states. Selecting Hong Kong returned India's states. No error is thrown — the data is silently wrong.

cities.csv had the same downstream corruption.

Root Cause

The country_id column was not derived from countries.csv IDs. The country_code column was always correct, but country_id diverged for ~148 countries starting alphabetically around Germany.

Fix

Regenerated country_id in both CSVs by mapping country_code (ISO) → correct id from countries.csv.

• states.csv — 4,581 rows corrected
• cities.csv — 105,446 rows corrected

Impact

Scenario	Impact
Fresh local setup / CI	✅ Fixed — correct geo data on first seed
Existing seeded deployment	✅ No impact — import script skips non-empty tables

Testing

-- Verify India's states return correctly
SELECT * FROM states WHERE country_id = 102 LIMIT 5;
-- All rows should have country_code = 'IN'

Note

Supersedes #1681 — this PR isolates only the geo-data fix.

Warning

Review limit reached

@YogeshK34, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 50 minutes and 4 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.
