refactor(ENG-276): Extract vault PDA derivation into INIT-VAULT function

[alnoki]

Changes

1. Extract vault PDA derivation and address verification from
   register.s into a new init_vault function, eliminating
   duplicated logic between base and quote vault paths
2. Add token_program_id and token_program_is_2022 fields
   to RegisterMarketFrame so INIT-VAULT receives the owning
   token program via the frame instead of a pre-loaded syscall
   register
3. Add acct field to RegisterMarketFrame for persisting the
   account pointer across the INIT-VAULT syscall
4. Track whether each token program is Token 2022 in both the
   base and non-duplicate quote token program paths
5. Add RETURN_SUCCESS constant to entrypoint for checking
   INIT-VAULT call results
6. Add BOOL_FALSE and BOOL_TRUE constants to memory
7. Remove e_invalid_quote_vault_pubkey error label from
   error.s (INIT-VAULT inlines the error return, branching
   on vault_index to select the correct error code)
8. Add INIT-VAULT pseudocode algorithm and "Vault initialization"
   section in markets.md
9. Rename .pubkey to .address in REGISTER-MARKET pseudocode
   for consistency with assembly field names
10. Add CreateAccountHappyPathToken2022QuoteDup and
    CreateAccountHappyPathToken2022QuoteNonDup integration tests
11. Update layout.md file tree with init_vault.s
