Update deps; fix file_size scientific notation bug

Float.round/2 can return 1000.0 at unit boundaries, which Elixir's
string interpolation renders as "1.0e3" (scientific notation). Switch to
:erlang.float_to_binary/2 with decimals: 1 to always produce decimal output.

Also updates mix.lock for latest dep versions including exqlite fork.
