Fix wolf.sh update_field(): scope field search to the app's own block

update_field() searched a blind +/-25-line window around an app's
name = '...' line to find and rewrite its mounts/env field. Once app
blocks got shorter (e.g. after collapsing a 3-line mounts array into
one line), two adjacent apps' blocks could end up close enough that
the window reached into a neighboring app's block instead — splicing
that block's own field or, worse, eating into its
[profiles.apps.runner] table header.

Confirmed live: this corrupted config.toml into invalid TOML and
crash-looped Wolf outright:

  ERROR | Unhandled exception: Error while parsing table header:
  cannot redefine existing table 'profiles.apps.runner'

Fix: bound the search to the enclosing [[profiles.apps]] block only —
walk backward from the name line to the nearest [[profiles.apps]]
header, forward to the next [[profiles.apps]] or [[profiles]] header,
and only look for the field within that range. Never crosses into a
neighboring block regardless of how short either one is.
