feat: implement per-market admin action timelock functionality and as…

close #850

Ran command: `python3 -c "
import os

filepath = 'contracts/predictify-hybrid/src/lib.rs'
with open(filepath, 'r') as f:
content = f.read()

First, remove the previously incorrectly injected functions

bad_funcs = ''' pub fn initialize(env: Env, admin: Address, platform_fee_percentage: Option, _allowed_assets: Option<soroban_sdk::Vec

>) -> Result<(), Error> {
if env.storage().persistent().has(&Symbol::new(&env, SYM_PLATFORM_FEE)) {
return Err(Error::InvalidState);
}
let fee_percentage = platform_fee_percentage.unwrap_or(crate::config::DEFAULT_PLATFORM_FEE_PERCENTAGE);
if fee_percentage < crate::config::MIN_PLATFORM_FEE_PERCENTAGE || fee_percentage > crate::config::MAX_PLATFORM_FEE_PERCENTAGE {
panic_with_error!(env, Error::InvalidFeeConfig);
}
env.storage().persistent().set(&Symbol::new(&env, SYM_ADMIN), &admin);
env.storage().persistent().set(&Symbol::new(&env, SYM_PLATFORM_FEE), &fee_percentage);
Ok(())
}

pub fn deposit(env: Env, user: Address, asset: ReflectorAsset, amount: i128) -> Result<types::Balance, Error> {
    crate::balances::BalanceManager::deposit(&env, user, asset, amount)
}

pub fn withdraw(env: Env, user: Address, asset: ReflectorAsset, amount: i128) -> Result<types::Balance, Error> {
    crate::balances::BalanceManager::withdraw(&env, user, asset, amount)
}

pub fn get_balance(env: Env, user: Address, asset: ReflectorAsset) -> types::Balance {
    crate::balances::BalanceManager::get_balance(&env, user, asset)
}'''

content = content.replace(bad_funcs, '')

Now inject it into impl PredictifyHybrid {

insert_target = 'impl PredictifyHybrid {'
insert_pos = content.find(insert_target)

if insert_pos != -1:
insert_pos += len(insert_target)
content = content[:insert_pos] + '\n' + bad_funcs + '\n' + content[insert_pos:]

with open(filepath, 'w') as f:
f.write(content)

Edited pr_documentation.md

I have generated the PR documentation following your requested template and saved it as an artifact.

In addition to preparing the PR documentation, I have also completed the final patches to lib.rs to fix the test suite. Specifically:

1. Re-injected the accidentally removed initialize, deposit, withdraw, and get_balance methods directly into the impl PredictifyHybrid block.
2. Registered the missing IdempotentBatchAlreadyApplied variant in err.rs and the PlaceBetsIdem data key in storage.rs.
3. Moved the MedianResolutionResult struct to the proper file scope so it could be compiled as a #[contracttype].

You can view the full PR documentation in the created artifact here: pr_documentation.md. Feel free to review it, and let me know if you would like me to adjust any sections!
