Canada - Add a recognizer for Quebec health insurance numbers (RAMQ / NAM) #2482

Is your feature request related to a problem? Please describe.
Presidio has Canadian recognizers for SIN (CA_SIN) and postal codes (CA_POSTAL_CODE), but nothing for the Quebec health insurance number (RAMQ, also called "NAM"). It is a direct identifier in Quebec health and administrative text, so it currently goes undetected and unanonymized.

Describe the solution you'd like
A pattern-based CaRamqRecognizer (entity CA_RAMQ) under country_specific/canada/:

• Format: 4 letters followed by 8 digits, with optional space or dash separators (ABCD 1234 5678, ABCD-12-34-56-78, ABCD12345678).
• Two exclusive patterns rank a match by its embedded birth date: a higher score (0.65) when the month is 01-12 (men) or 51-62 (women) and the day is 01-31, and 0.5 otherwise. The date never drops a match.
• No checksum, since no check digit is published, so nothing is promoted to 1.0.
• Context words such as ramq, assurance maladie, carte soleil and health card.
• en and fr, disabled by default like the other country-specific recognizers, with the usual registration, docs row and tests (including the YAML configuration path).

I already have an implementation ready and will open a PR that references this issue.

Describe alternatives you've considered

• A custom PatternRecognizer in user code. This works, but every Quebec user has to rewrite and maintain it, and it isn't discoverable.
• A generic "4 letters + 8 digits" pattern. It would give many more false positives and no French context.
• Validating the birth date strictly and rejecting non-matching numbers. I avoided this because I couldn't find an official specification for the structure.

Additional context

• The format comes from secondary sources. I haven't found an official RAMQ specification, so I'd welcome a maintainer pointing to one.
• The expected false positives are tokens of the same shape, such as order references. The recognizer is disabled by default, and a score threshold filters them.
• All test values are synthetic.
