Fix West African mobile money phone number validation regex

[matthappens]

Summary

Updated the phone number validation regex pattern for West African mobile money numbers to enforce country-specific digit requirements instead of a generic range.

Key Changes

• Senegal (+221): Changed from flexible [0-9]{8,10} to strict [0-9]{9} (9 digits after country code)
• Ivory Coast (+225): Changed from flexible [0-9]{8,10} to strict [0-9]{10} (10 digits after country code)
• Benin (+229): Changed from flexible [0-9]{8,10} to strict [0-9]{8,9} (8-9 digits after country code)

Implementation Details

The previous regex pattern ^\+(221|225|229)[0-9]{8,10}$ accepted any combination of 8-10 digits for all three countries, which was too permissive and could allow invalid phone numbers. The updated pattern ^\+(221[0-9]{9}|225[0-9]{10}|229[0-9]{8,9})$ now validates each country code with its correct digit length requirements, improving data quality and reducing invalid number submissions.

Greptile Summary

This PR tightens the West African mobile money phone number validation regex in both openapi.yaml and mintlify/openapi.yaml, replacing a single permissive range with per-country digit length requirements.

• Senegal (+221): Changed from [0-9]{8,10} to [0-9]{9} — correctly enforces 9 local digits (e.g., 77 XXX XX XX).
• Ivory Coast (+225): Changed from [0-9]{8,10} to [0-9]{10} — correctly reflects the post-2021 10-digit format (after the national renumbering expanded from 8 to 10 digits).
• Benin (+229): Changed from [0-9]{8,10} to [0-9]{8,9} — the range is intentional to accommodate both the legacy 8-digit format and the newer 9-digit format introduced in 2023.
• Both openapi.yaml and mintlify/openapi.yaml are updated identically and kept in sync.
• The provided example (+221781234567) continues to satisfy the new regex.
• Note: this is a validation-tightening breaking change — API clients sending numbers that matched the old (more permissive) regex but fall outside the new per-country ranges will now receive validation errors. This appears intentional per the PR description.

Confidence Score: 5/5

• This PR is safe to merge; the regex correctly enforces real-world digit requirements for each country and both spec files are kept in sync.
• The change is a small, targeted regex update in two YAML spec files with no logic or code changes. The new patterns correctly reflect documented national numbering plans (9 digits for Senegal, 10 for Ivory Coast post-2021, 8-9 for Benin during its transition). Both files are updated identically. The only consideration is that this intentionally tightens validation, which is the stated goal of the PR.
• No files require special attention.
