fix(common): Reject hex and trailing chars in ParseFloatPipe isNumeric

Replace !isNaN(parseFloat(value)) with strict regex matching valid float syntax (/^-?(?:\d+\.?\d*|\.\d+)(?:[eE][+-]?\d+)?$/).

Previously, parseFloat('0xFF') returned 0 and passed validation. Now hex (0xFF), octal (0o17), binary (0b101), and trailing characters (123abc) are correctly rejected.

Consistent with ParseIntPipe which uses the same regex approach.

Added 4 test cases: hex string, binary string, Infinity, -Infinity.
