# Prospecting Contact Scraper — Fix Enum + Improve Regex

## Problem 1: DB Enum type mismatch

`ProspectContact.contact_type` is defined as a Python Enum (`contacttype`) in the model, but the DB column was created as a plain `VARCHAR` in the migration. When SQLAlchemy inserts, it casts to `::contacttype` which doesn't exist in PostgreSQL.

**Error:** `type "contacttype" does not exist`

**File:** `app/modules/prospecting/models/prospect_contact.py`

**Fix options:**
- A) Change the model column from `Enum(ContactType)` to `String` to match the migration
- B) Create an Alembic migration to add the `contacttype` enum to PostgreSQL

Option A is simpler and consistent with how the scraper creates contacts (using plain strings like `"email"`, `"phone"`).

## Problem 2: Phone regex too loose and Luxembourg-specific

The phone pattern `(?:\+352|00352)?[\s.-]?\d{2,3}[\s.-]?\d{2,3}[\s.-]?\d{2,3}` has two issues:

1. **Too loose** — matches any 6-9 digit sequence (CSS values, timestamps, hex colors, zip codes). On batirenovation-strasbourg.fr it found 120+ false positives.
2. **Luxembourg-only** — only recognizes `+352`/`00352` prefix. This is a French site with `+33` numbers.

**File:** `app/modules/prospecting/services/enrichment_service.py:274`

**Fix:** Replace with a broader international phone regex:
```python
phone_pattern = re.compile(
    r'(?:\+\d{1,3}[\s.-]?)?'       # optional international prefix (+33, +352, etc.)
    r'\(?\d{1,4}\)?[\s.-]?'         # area code with optional parens
    r'\d{2,4}[\s.-]?'               # first group
    r'\d{2,4}(?:[\s.-]?\d{2,4})?'   # second group + optional third
)
```
Also add minimum length filter (10+ digits for international numbers) and exclude patterns that look like dates, hex colors, or CSS values.

## Problem 3: Email with URL-encoded space

The scraper finds `%20btirenovation@gmail.com` (from an `href="mailto:%20btirenovation@gmail.com"`) alongside the clean `btirenovation@gmail.com`. The `%20` prefix should be stripped.

**File:** `app/modules/prospecting/services/enrichment_service.py:293-303`

**Fix:** URL-decode email values before storing, or strip `%20` prefix.
