fix(meltano): remove catalog capability and switch elt to run

The `catalog` capability forced Meltano to run --discover and generate
a catalog file (tap.properties.json) before each extraction. This fails
because our Singer SDK taps emit schemas inline and don't need external
catalog files. Removing the capability makes Meltano invoke taps
directly without catalog generation.

Also switch from deprecated `meltano elt` to `meltano run` for
Meltano 4.x compatibility.
