refactor(twap_oracle): match instruction function order to Instruction enum

Browse Source 
`idl-gen` emits IDL instructions in source order, and `spel` uses each
instruction's IDL position as its serde variant index. When the
`#[instruction]` function order diverges from the `twap_oracle_core::Instruction`
enum order, spel addresses the wrong instruction.

Move `update_current_tick` ahead of the TWAP-computation instruction so the
function order in twap_oracle.rs lines up with the enum variant order, and
regenerate artifacts/twap_oracle-idl.json to match.

No behavioral change — the instruction bodies are unchanged, only reordered.
