fix(functions): add missing regions to V2_REGION_TO_TIER pricing map (#9697)

The V2_REGION_TO_TIER mapping was missing several Cloud Functions regions
that are officially supported, causing issues when deploying functions
with minInstances to these regions:
- canCalculateMinInstanceCost() returns false, showing generic warning
- monthlyMinInstanceCost() throws TypeError if called without guards

Added missing Tier 1 regions:
- africa-south1 (Johannesburg)
- europe-southwest1 (Madrid)
- europe-west8 (Milan)
- europe-west9 (Paris)
- me-west1 (Tel Aviv)
- us-east5 (Columbus)
- us-south1 (Dallas)

Added missing Tier 2 regions:
- asia-south2 (Delhi)
- australia-southeast2 (Melbourne)
- europe-west10 (Berlin)
- europe-west12 (Turin)
- me-central1 (Doha)
- me-central2 (Dammam)
- northamerica-northeast2 (Toronto)
- southamerica-west1 (Santiago)

+- Fixed pricing calculation for Cloud Functions deployed to newer regions (africa-south1, europe-west8, me-west1, and others) when using minInstances. (#9696)
 - Removed MCP tools and prompts that required Gemini in Firebase terms of service.
 - Fixes an issue where the `--only` flag was not always respected for `firebase mcp`
 - Removed timeout when connecting to Cloud SQL. Hopefully, should mitigate issue #9314. (#9725)
