fix(rollup): allow specfiying full filter directives in logs

[SuperFluffy]

This patch removes the pre-set astria-conductor= and astria-composer= prefixes in the *-LOG env vars set for conductor and composer.

The environment variables ASTRIA_CONDUCTOR_LOG and ASTRIA_COMPOSER_LOG don't merely allow setting log levels but allow much more expressive filtering of targets (like modules), span names, span-fields or values of span-fields.

For example, I used the following filter directives to test changes to conductor:

filterDirectives: "[{config}]=info,[{sequencer_block.height=1951}]=info,[{reconstructed_block.height=1951}]=info,[{block.height=1951}]=info"
