feat(twap-oracle): implement CreatePriceObservations instruction

Browse Source 
Adds the CreatePriceObservations instruction to the TWAP oracle program.
The instruction initialises a PriceObservations PDA for a given price
source account and time window, writing the initial tick and timestamp
as the first entry.

Key design decisions:

- Per-window accounts: each (price_source, window_duration) pair maps to
  a distinct PriceObservations PDA. The window duration is baked into the
  PDA seed so a single price source can support multiple TWAP windows
  (24h, 7d, 30d) at independent sampling rates without sharing a buffer.

- window_duration not stored on struct: it is implicit in the PDA address.
  Any reader that located the account already knows the window duration
  used to derive it. Storing it would be redundant.

- Authorization is implicit: the PriceObservations PDA is derived from
  the price source account ID, so is_authorized = true on the price source
  proves the caller controls it without a redundant authority field.

- Impersonation is prevented by the PDA check: passing a controlled price
  source with a victim's observations account ID fails immediately because
  the computed PDA (from the attacker's source) does not match.

Closes #126
