The SSN regex used the character classes [1,2] and 2[A,B], which also
match a literal comma. fr_ssn(', 84 12 76 451 089') was therefore
accepted as valid. Drop the commas ([12] and [AB]); valid SSNs are
unaffected.
ind_pan used re.match(r"[A-Z]{5}\d{4}[A-Z]{1}", ...) with no trailing $,
so any string starting with a valid PAN was accepted -- e.g.
ind_pan('ABCDE9999KEXTRA') returned a match. Anchor the pattern with
^...$, matching the ind_aadhar style just above it.

Two small regex-correctness fixes in the i18n validators; each currently lets invalid input through. Both are covered by new regression tests that fail on
masterand pass with this change.ruffis clean and the full suite passes.ind_pan— trailing characters acceptedind_panusedre.match(r"[A-Z]{5}\d{4}[A-Z]{1}", value)with no trailing$.re.matchonly anchors the start, so any string that begins with a valid PAN was accepted:Anchored the pattern with
