Add total_settled_amount_all() summing settled amount across every lifecycle status

[Jagadeeshftw]

📌 Description

total_liquidity_all() sums total liquidity across every asset in one call, and contract_info() gives a version/paused/fee/count snapshot — but there's no single-call equivalent summing total_settled_amount(status) across every status, so a dashboard wanting an overall settled-volume figure has to call the per-status variant once per known status and sum client-side.

🧩 Requirements and context

• Add total_settled_amount_all(env) -> i128 summing settled amount across every settlement status, mirroring total_liquidity_all()'s pattern.
• No change to the existing per-status total_settled_amount(status).
• Consider whether it belongs alongside contract_info()'s snapshot fields, or stays a standalone read — pick one and be consistent with existing naming conventions.

🛠️ Suggested execution

• Add the new pub fn to src/lib.rs, reusing whatever aggregate-tracking storage.rs maintains per status.
• Add tests in src/test.rs verifying the sum matches manually adding every per-status call.
• Update the README's Settlement table.

✅ Acceptance criteria

• total_settled_amount_all() returns the correct cross-status sum.
• Existing per-status reads are unaffected.
• Documented in the README.

🔒 Security notes

Read-only addition; no new attack surface.

📋 Guidelines

• Minimum 95% test coverage
• Clear documentation
• Timeframe: 96 hours

@GBOYEE appreciate the enthusiasm on the total_settled_amount_all() work, but you've already got 6 open assigned issues here plus requests posted across 20+ others — that's well past a sustainable load for one contributor. let's get some of your existing assignments merged first before adding more to the queue.

@GBOYEE update on the cap: on review, #99/#98/#91 already had a PR referencing them (PR #102), so those freed up. i used the freed slots for your three oldest pending requests (#97, #95, #81), which puts you back at the 6-issue cap. this one (#78) will have to wait until you close out some of what's assigned. thanks for the patience.
