Replace the hardcoded validTableNames allowlist with a regexp that
only allows [a-z0-9_] characters. This prevents SQL injection without
requiring maintenance of a separate allowlist when new tables are added.

The getTableCount method used fmt.Sprintf to interpolate a table name directly
into a SQL query. While currently only called with hardcoded names, this is a
dangerous pattern. Added an allowlist of valid table names and return an error
for unrecognized names.
