lexer: format control-character codepoint in error messages as hex

The three "invalid character" messages render the offending rune as
"\u" + %04d, which prints the byte value in decimal. The "\u" prefix
implies a Unicode codepoint, so anything past U+0009 comes out wrong:
0x0E reports as "", 0x1F reports as "1", etc.

Switch to %04x so the printed codepoint matches the actual character.

The existing yml tests only exercised 0x07 and 0x00, where decimal and
hex render the same; added one for 0x0E so the difference is covered.
