chore(query-nodes): camel case paths filter

[thmsobrmlr]

Problem

We want to clean up our query schema. See also #19541.

Changes

This PR camel cases all pathFilter properties.

•  edge_limit
•  paths_hogql_expression
•  include_event_types
•  start_point
•  end_point
•  path_groupings
•  exclude_events
•  step_limit
•  path_replacements
•  local_path_cleaning_filters
•  min_edge_weight
•  max_edge_weight
•  funnel_paths
•  funnel_filter - the filters themselves aren't touched in any way. probably best to do so when we implement the hogql version of the query

How did you test this code?

Verified setting, saving and loading an insight with this filter works
