Refactor filtering arguments in DFG functions to use 'whereNoun'

[Affie]

Reasons:

• Autocomplete:

julia> listVariables(fg; where
whereLabel=
whereSolvable=
whereTags=
whereType=

• natural language eg. listVariables(fg, whereLabel = startswith("x")) list variables where its label starts with "x"

Pull request overview

Refactors DFG listing/filtering APIs to use where*-prefixed keyword arguments (e.g. whereLabel, whereTags) to improve discoverability/autocomplete and make call sites read more naturally.

Changes:

• Renamed filter keyword arguments across core list/find/state/blobentry APIs to where* variants.
• Updated GraphsDFG implementations and related helpers (ls, lsf, getSubgraph, getBiadjacencyMatrix, blobentry accessors) to pass through the new keywords.
• Updated tests and NEWS entry to reflect the renamed API.
