fix(prospecting): fix scan-jobs batch endpoints and add job tracking

- Reorder routes: batch endpoints before /{prospect_id} to fix FastAPI
  route matching (was parsing "batch" as prospect_id → 422)
- Add scan job tracking via stats_service.create_job/complete_job so
  the scan-jobs table gets populated after each batch run
- Add contact scrape batch endpoint (POST /contacts/batch) with
  get_pending_contact_scrape query
- Fix scan-jobs.js: explicit route map instead of naive replace
- Normalize domain_name on create/update (strip protocol, www, slash)
- Add domain_name to ProspectUpdate schema
- Add proposal for contact scraper enum + regex fixes

+# 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.
+
