taffybar: pull in WirePlumber/OpenAI/Anthropic memory fixes

Bump the vendored taffybar submodule to 17337fec and re-lock the config
flake's git+file taffybar input, pulling in three fixes just merged to
taffybar/taffybar master:

- WirePlumber: fix use-after-free windows in SpaPod handling (#684) --
  pod lifetimes: deep-copy escaping borrows, touchManagedPtr parents
- OpenAIUsage: destroy replaced menu to fix GObject leak (#682)
- AnthropicUsage: cache per-file transcript extractions across polls (#683)

The first is a genuine heap-safety fix; the latter two curb the usage
widgets' unbounded memory growth.
