Fixed incorrect fallback behavior in keyword lexer functions. Four
functions (lex_e_keyword, lex_o_keyword, lex_r_keyword, lex_n_keyword)
were incorrectly calling lex_name() instead of lex_keyword() when
keywords didn't match.
When a PDF contains an unrecognized word starting with e/o/n/R
(e.g., "endob" instead of "endobj"), the lexer should fall back to
generic keyword parsing (Token::Keyword(bytes)), not name parsing.
Names always start with /, so calling lex_name() on input without
a leading / would incorrectly skip the first byte.
