update_mint_params_by_mint_authority

Internal GLAM Mint authority path for mint-parameter updates that are not owner-timelocked.

Handler narrative

Load the GLAM state or program account required by the instruction and verify the signer.
Apply the requested state, policy, pricing, or system action after enforcing owner/delegate checks.
For glam mint program's use only, timelock is not enforced

The submitted accounts must match the declared account list, signer requirements, writable requirements, fixed program addresses, and account relationships shown below.
The GLAM state account is the source of truth for owner, enabled integrations, delegate permissions, policies, assets, borrowable assets, timelock settings, mint linkage, and pricing records.
Owner-level actions must be signed by the state owner unless the instruction is explicitly an integration callback, mint-authority callback, delegate action, or emergency access update.
Configuration changes must pass owner or authorized-manager checks and, when the state or mint timelock is active, must follow the propose/apply timing model instead of taking effect immediately.

Account	Role	Description
glam_state	writable	State account owned by the GLAM Protocol program; it records vault configuration, policies, and pricing records.
glam_mint	read-only	Token-2022 mint associated with the GLAM mint or tokenized vault.
glam_mint_authority	signer	Token mint account used by the instruction.

Argument	Type	Notes
params	vec<EngineField>	List of mint engine fields updated through the mint-authority path. Fields: `name: EngineFieldName`; `value: EngineFieldValue`

No external integration enablement is required beyond the program-level functionality involved in this instruction.
Only the owner is expected. Delegates do not receive this capability by being added; it must be granted explicitly if supported.

No additional cross-instruction constraint is documented beyond account initialization, authority checks, and policy validation.
